Laser pointers are small, hand-held devices that are designed to produce light beams. Today, consumer laser pointers are mostly used as presentation pointers, for astronomy and as toys for cats. The most familiar application of the laser pointer would be the presentation pointer.
During the 1990s, it was common for professionals and college students alike to use large, bulky overhead projectors to present information. Overhead transparency slides typically had plenty of data crammed into a small space, so presenters found it necessary to highlight their main points.
By then, laser pointers had become affordable and were sold at many stores. Therefore, they were a good fit as presentation pointers.
In the field of astronomy, laser pointers have become particularly useful tools. Green laser pointers are used to point out celestial objects, including stars and constellations.
Those who are used to seeing presentation pointers may be surprised at how far light beams from green laser pointers could travel, into the night sky. There are a number of reasons why green laser beams can be easily seen at night.
Firstly, our human eyes are especially sensitive to green light. Moreover, green laser pointers for astronomy usually have a relatively high-power output of 5 milliwatts (mW) or more. As green light travels through the air, it gets scattered away from the main beam direction by air and dust particles, allowing you to view it from the side.
Take note that in many states and countries, the use of high-powered laser beams above 1 mW is highly regulated and restricted. You may be required to apply for a permit to own and operate one. If in doubt, check with your local authorities before making a purchase.
Laser pointers are also used as toys for cats. This is due to the feline creatures’ never-ending obsession with the laser beam! Cats possess a natural predatory instinct, and will usually chase after anything that moves.
When you shine a laser beam in the room, your cat will run after it and try to “catch” it. The only problem is that this builds frustration in your cat. There is nothing more futile than chasing after a laser light that cannot be caught!
Veterinarians recommend that if you wish to use laser toys on your cat, hide some treats around the house, and occasionally, shine a beam on one of these treats. This will simulate the cat’s behavior in the wild, where it can look forward to catching its prey. Having said that, it is still a good idea to buy tangible toys that your pet cat can lay its paws on.

- Move and present freely from as far as 20 meters (65 ft) away. Perfect for medium to large-size...
- The R500 pairs with the powerful Logitech presentation app so you can customize button functions,...
Logitech is known to produce excellent computer peripheral devices, and the R500 is no exception. The Logitech R500 is a very versatile and advanced presentation remote.
First released in May 2018, it has quickly become a popular model for professional presenters. It is highly compatible with various operating systems, computers and devices, and priced relatively affordably.
It is also known to work well with projector screens and on walls. Previously, we did a review on three top Logitech presentation pointers, and the R500 was the winning choice.
The Logitech R500 Presentation Pointer is designed to work with most presentation software, including PowerPoint, Prezi, Google Slide, Keynote, and PDF. It also works with Windows, Mac OS, Android, and iOS operating systems.
This gives it a range of flexibility for use in different settings and eliminates the need for customers to buy different pointers for different systems.
Connectivity is provided in two choices – you could either use its wireless or USB receiver to connect with your computer, or connect using Bluetooth. The device has an app that lets you track battery life, customize the button functions, and set a timer for presentations.
We like the presentation timer feature, which we think will be helpful to any seasoned or new presenter alike. The textured grip gives you a good feel of the pointer, and the controls are fairly easy to use.
This model also has a good operating range of 65 feet (20 meters), which is adequate for meeting rooms and even lecture halls.
Some customers commented that their R500’s controls started wearing out after a year of intensive use. This may be a concern for those who give presentations frequently, but otherwise, there was no other aspect of this product that we didn’t like.
- Compatibility with many operating systems (Windows, Mac OS, Android, and iOS)
- And most presentation software (PowerPoint, Prezi, Google Slide, Keynote, and PDF)
- Connect via Bluetooth (low energy) or USB receiver
- Presentation timer feature
- Logitech presentation software
- Capable for 12 months on a single AAA battery
- Power-saving mode for extra use
- Textured grip and easy controls
- Good operating range (65 feet or 20 meters)
- Buttons could wear out after long-term intensive use

- Smart time management - Spotlight reminds you when it's time to wrap up. The presentation remote...
The Logitech Spotlight Presentation Remote was released in 2017 and proved to be a hit. It is an advanced remote that lets you highlight or magnify data with a spotlight (hence the name).
Its cursor can work as a mouse; you could use it to play and pause videos, click on web links, and switch between different modes. This device is compatible with both Mac and Windows operating systems and works with popular presentation software such as Google Slides, Prezi, and PowerPoint.
It is also designed to work with smart TV monitors. The Logitech Spotlight was our recommended presentation remote for TV screens when we did a comparison with a few other models.
Your overall experience with the product starts with its sleek, user-friendly design. We find the gold color option to be particularly appealing and definitely makes the device stand out from other competitors.
However, another area that stands out is its compatibility with LCD and LED TV screens. Not many presentation pointers work well with TV screens as the monitors are designed to absorb incoming light.
Moreover, non-compatible laser pointers could damage your television screens. The Logitech Spotlight solved this problem and is our top recommendation of presentation pointers for TV screens.
The device has an excellent long-range of 98 feet (30 meters), which easily wins most presentation pointers hands-down. This will be useful for those who have to present in large halls.
It also allows you to connect to your computer using both Bluetooth and a wireless USB receiver. The quick-charging capability is a bonus for professionals who are constantly on the go.
Some customers claim that they are able to continue presenting for hours after just a minute of charging! Meanwhile, the timed alerts are very useful for keeping time for your presentation.
The somewhat steep price of this remote makes it expensive for those who do not present frequently. Another shortcoming is that the Logitech Spotlight does not have magnifying and highlighting functions for iPhones.
However, we think that regular presenters will find it a worthwhile investment due to its compatibility with most presentation software and operating systems, as well as LED screens.
- Highlighting and magnifying function
- Compatible with TV, LCD screens, even via video conference
- Excellent range of 98 feet (30 meters)
- Work on Mac, Windows, and Google Slides, Prezi, PowerPoint
- Dual transmission – Bluetooth and USB receiver
- Quick charging
- Smart timed alerts
- Mouse-like cursor control
- Steep price
- Lack of highlighting and magnifying ability for iPhones

- POWERFUL GREEN LASER, highly visible green laser in any environments with improved accuracy, reaches...
- CONVENIENCE & COMPATIBILITY, comes with a remote control to easily switch laser on and off;...
The Pinty Green Laser Scope is a highly recommended pointer for astronomy use.
It was designed to work as a laser scope for hunting rifles, featuring an aerospace-grade aluminum housing; and figure-of-eight dual-hole mount or 20mm weaver mount.
Its upgraded optic results in a bright and sharp green laser light, although its power output is less than 5mW. The Pinty Green Laser Scope is quite easily the best laser pointer for astronomy, even when compared to other popular models.
From an astronomer’s point of view, the strong green laser is the standout feature as it aids in stargazing. Green lasers are known to be the best for astronomy as our eyes are very sensitive to green light.
Furthermore, as green light travels through the air, the light gets scattered away from the main beam by dust and air particles, allowing you to see it from the side.
Take note that this laser pointer’s battery is not rechargeable, meaning you would have to bring along replacements. Thankfully, the included Lithium-ion battery can last for several hours.
We liked how durable this laser pointer is and how its mounting mechanism was designed to be simple. It’s easy to replace its battery while still mounted on a rifle, and it boasts an extremely high reaching distance of 980 to 1,000 feet (298 to 304 meters).
The Pinty Green Laser Scope could even be controlled by remote.
The laser scope is difficult to adjust to zero, which may be an issue for those who use it in hunting. The weaver mount was also a design flaw as users commented it fell off too easily.
The lack of a child lock feature and a non-rechargeable battery are also drawbacks that we think could be improved upon in future models.
- Excellent green laser for astronomy and stargazing (532 nm wavelength)
- The high reaching distance of 980 to 1,000 feet (298 to 304 meters) although its power output is less than 5mW
- Very durable and sturdy construction
- Simple mounting mechanism
- May be controlled by remote
- Poorly-designed weaver mount
- Non-rechargeable battery
- Lack of child lock
- Difficult to adjust to zero

4. Safe For Pets: Dialeesi Laser Pointer
The Dialeesi Laser Pointer is our choice of laser pointer toys that are safe for use with cats and dogs. Earlier on, we reviewed this device together with a few competitors and found it to be the best option for laser pointer pet toys.
Importantly, this pointer has a low power range of between 1-5 mW and is designed to be used at home, provided you do not shine it directly into your pets’ eyes. It is also an updated model, where the manufacturer claims it has addressed some issues with earlier versions, including button functions and battery connections.
The Dialeesi is an interactive laser toy that possesses multiple light functions. The red laser light is meant to mimic hunting in the wild so that your cat will stalk and chase after it.
The white LED flashlight works as an ordinary flashlight to illuminate dark areas, while the UV detector is useful for finding pet stains and examining currency bills for counterfeits.
Since the pointer is designed for indoor use, its optimal range is only 30-50 yards (27-45 meters).
The laser pointer is housed in a rather elegant unit that looks just like your regular flashlight. We liked that it offered a strong red laser beam despite having a low power rating, and is safe for human and animal use.
The additional cat toys, including a screaming squeaky mouse and a lanyard, were also great bonuses. It is very convenient to recharge this device by a USB cord, and its lightweight makes it easy to hold.
The Dialeesi’s battery doesn’t last long. Thankfully, it uses an AA battery that could be easily replaced. Some customers also claim that the battery may not hold a charge.
- Use an AA battery that can be recharged by USB
- Strong red laser and UV detector for finding pet stains
- The low power output that is safe for human and animal use
- Lightweight and sturdy design

The Logitech Professional Presenter R800 is another promising device that uses a green laser. Similar to the PR10-G, it has a working range of 100 feet (30 meters) and is plug-and-play.
The R800 works with PowerPoint and other presentation software and seems to perform better on a projection screen rather than on a TV screen.
The R800 is a great option for those who need to present in large conference rooms. Its green laser pointer could be used to highlight a specific area on your slide; all you have to do is press on the aiming button.
The vibration alerts will be much appreciated by seasoned and novice presenters alike. These vibrations may be set at 2 minutes, 5 minutes and 10 minutes intervals, giving you a good idea of whether you are keeping to the schedule.
The R800 runs on 2 AAA batteries, which may last for over 1,000 hours if you do not use the laser pointer function. Moreover, the device’s USB receiver may be stored in a compartment in the main unit when not in use, so you would not misplace it.

- The green laser pointer is highly visible
- Plug and play design
- Run on 2 AAA batteries
- Vibration alerts
- LCD display with timers
- Good range of 100 feet (30m)

The Ultimate Buying Guide for Laser Pointers
There are many factors determining the usefulness of a laser pointer. There are many ways to use a laser pointer, and so a good laser pointer should be well-suited to the purpose it was intended for.
Key features that set apart one laser pointer from another include its power output, the color of a laser beam, range, adjustability, accessories, size, and price.
Key Features of a Good Laser Pointer
1. Power Output
Power output is a feature that varies greatly depending on what the pointer is meant to be used for. Presentation pointers require a fairly low power output of 5 mW or less; laser pointers for astronomy may require an output of more than 5 mW; while laser toys for cats should have a low wattage of only around 1 mW.
Astronomy laser pointers are high-powered as they have to be projected far into the night sky and point out celestial objects. In contrast, toys for cats should have low-powered lasers in order to be safe for human and animal use.
Presentation pointers use a fairly low output as they have to be safe for the consumer and indoor use, and any accidental shining of the beam into human eyes could be hazardous for health.
2. Color of Laser Beam
The most common laser color people are familiar with is red. Red laser pointers are frequently used for presentations and as toys for cats and dogs. However, green pointers are common for astronomy as our eyes are more sensitive to green light.
Green lasers also get dispersed by air and dust particles, allowing you to view it from the side. Some presentation pointers may also feature white spotlights for highlighting and magnifying. This makes it more relaxing to the eyes.
3. Range or Adjustability
The range is yet another area where pointers vary a lot.
While pointers for astronomy could reach up to a thousand feet (300 meters), laser pointers for cats may only reach up to 50 yards (45m). Presentation pointers could typically reach between 50 to 100 feet (15–30m), which is ideal for lecture halls and indoor spaces.
A related feature is adjustability, especially for astronomy laser pointers. These devices have a focus that can be adjusted according to lighting conditions, which is helpful when looking at constellations at night.
4. Accessories
While accessories may not be the first criteria you look at in a laser pointer, they could be a tie-breaker when comparing laser pointers of similar specifications. Professional presenters may value accessories such as a carrying case and fast-charging USB cable.
On the other hand, cat owners would be more inclined towards accessories such as a rubber toy mouse for their pets to play with. Hunting hobbyists will prefer accessories such as mounts for their laser scope. Therefore, manufacturers need to be clear about their target customers and what accessories to include with each product.
5. Size
Size is a feature in which most people would assume “smaller is better”. However, a high-powered laser scope such as those used with hunting rifles could be hefty and weigh up to 5 ounces (140 grams).
The key is to avoid getting devices that are considered heavy for their power output and purpose. For instance, presentation pointers that weigh over 3 ounces (85 grams) would be considered cumbersome and tiring to hold for long periods.
6. How Much Should I Spend?
In terms of cost, we have found that a handful of top-rated laser pointers would set you back by a significant amount. However, the vast majority of good laser pointers we reviewed on this site are affordably-priced. This means that if budget is a concern, you could still find high-quality laser pointers for your needs at comfortable prices.
Different Laser Pointer Colors
There are five common colors of lasers: red, orange, yellow, green, and blue. While other colors do exist, they aren’t usually found in laser pointers. This is because the color of the laser correlates to how high the wavelength is.
Thus, there’s a safety procedure when it comes to making laser pointers. We’ll discuss that under the “wavelength” section of this buyer’s guide.
Laser Pointer Safety Guidelines
Lasers generally aren’t dangerous unless misused. You’ll find that there isn’t a “safe” range for laser pointers, but there are power levels that don’t inflict as much damage.
Anything lower than 5 mW is safe for the human eye, as it gives the human enough time to blink and won’t damage any cones or rods found inside the eye. However, when that level gets higher than 5 mW, one flash into the eye can end up producing permanent eye damage, thus making it very dangerous if misused or by accident.
Who Makes The Best Laser Pointer?
The laser pointer market is quite competitive these days, with many brands entering the market. Nevertheless, some brands have established themselves as the go-to product in specific laser pointer categories.
When you think of presentation pointers, brands such as Logitech, Kensington, Targus, BEBONCOOL, DinoFire, and Doosl are the main ones which come to mind. Logitech, Targus, and Kensington have had decades of experience developing computer accessories, making them trusted brand names.
Newer brands such as BEBONCOOL, DinoFire, and Doosl have differentiated themselves by specializing in specific markets, such as video game controllers and presentation devices. Regardless of the years of experience, the brands above all have one strength in common – the production of professional quality presentation pointers that are safe for consumer use.
Laser pointers for astronomy are generally dominated by the Wickedlasers and Pinty brands. Wickedlasers specializes in powerful, handheld laser devices, which are specially designed to be visible in the night sky.
Pinty, meanwhile, focuses its efforts on developing laser scopes for rifles. Although they are popular for military and hunting use, Pinty’s laser pointers are also highly-capable for stargazing and have become a top choice among astronomers.
Laser pointer toys for cats tend to have many producers such as Dialeesi, Undercut Innovations, FYNIGO, and Laifoo. Many Chinese manufacturers have entered the laser pointer market in recent years.
As laser pointer toys for cats and dogs are required to have low wattage of around 1 mW, these companies are able to produce the devices at a relatively low cost and with economies of scale, thus offering consumers affordable prices. Some even throw in additional features such as a regular LED flashlight and a UV light, which may be used to look for pet stains.
FAQs
How does a laser pointer work?
Laser pointers work by projecting a small but powerful beam of light onto a surface. The first end of the laser features a mirror, and on the opposite end, is a semi see-through mirror rests. A flash tube will then use a light source, such as a laser beam, and shoot it to one end of the rod.
After this, when you press the power button, the tube will send atoms inside the rod and force it to point at the mirror. This results in it pointing towards the semi see-through mirror and exits the laser onto a surface. We have written a quite long article about how a laser pointer works.
How to fix a laser pointer?
When it comes to fixing a laser pointer, there may be a few ways to do it without having to bring it into a repair shop or replacing the whole unit. Here’s a list of a few fixes you can try at home:
- Try and replace the batteries. Sometimes, one fix to a unit that just suddenly stopped working is just a simple change of batteries. Choose fresh batteries.
- Disassemble the laser. Another way is to unscrew the unit and check to see if there is an issue with the circuit. You may be able to find replacement parts and order them online, though it may be cheaper to replace the whole unit.
- Remove the internal circuit board. Take out all parts and see if you can get the circuit board off. After this, you can replace it or see if there were any connectivity issues.
- Test all components of the laser – check to see if there are cut wires, if the circuit isn’t connecting, or see if there is a smaller issue.
- Trim the pot. Turn the potentiometer to the highest setting and power it with batteries. See if the laser has a continuous beam or if it’s clicking. If the pen shows any sign of weakness, then it’s likely that the unit will not work anymore.
How far can a laser pointer travel?
Laser pointers have an exceptional range compared to older models. When you think of a laser pointer, you may imagine the ones they used back in school.
However, with modern advancements in technology, lasers can now reach a bit farther while still retaining an intense beam of light.
The range of a laser pointer can be anywhere from 30 feet all the way to over 300 feet. You’ll find that a majority fall into the 30-foot category, as these ones are good for small presentations or meetings.
However, the most common one is the ones with a 100-foot range. These lasers are excellent for high school or college classes and feature a bright red laser that will show up on most backdrops.
Final Verdict
Laser pointers come in various colors and can be used for multiple applications. Whether you’re using it for fun or plan to use it at your next presentation, laser pointers will enhance your ability to keep your audience’s or pet’s attention. Hopefully, this article has helped you find at least one laser pointer that you liked.
