    Features for Safety First

    With any laser this powerful, proper safety practices must be taken in order to prevent injury or other accidents.

Please see the Safety & Best Use Practices below for more information on how to safely use the Radian Green Laser.

    Durability, Portability, & Other Extras

    Made of top-grade aluminum, the Radian Green Laser is highly durable and resistant to drops. To further prevent drops, a handy wrist strap is included. At just 6 inches (150mm) long, it's compact, lightweight, and easy to hold and carry. A convenient Radian-branded zip-up carry bag is included for protecting the laser during travel and storage.


    Safety & Best Use Practices

    With any laser, especially one as powerful as the Radian Green Laser, it's best to follow these Safety & Best Use Practices to prevent injury, accidental damage, and proper stargazing etiquette:

    • Never point the laser at someone's eye or face, including your own. Doing so can cause permanent damage to vision. Always keep the laser pointed up at the sky when using it for stargazing.
    • Keep the laser away from children at all times, and store the safety locking key in a separate location away from the laser when not in use.
    • Never point the laser at a magnifying glass, binoculars, a telescope, a mirror, or other reflective glass surfaces that could potentially magnify or reflect the laser beam.
    • Never point the laser at aircraft, and follow local laws and regulations about using a laser.
    • Use caution when pointing the laser at a solid surface for more than a few seconds, as it can cause objects to burn.
    • When at a dark sky location with other amateur astronomers nearby, it's best to ask permission to use the laser first, as doing so can ruin night vision for astronomy and/or long exposure images.
    • Do not keep the laser on for more than 30 seconds at one time as it can shorten the laser's useful lifetime.
    • Remove the battery when the laser is not in use.

Excellent for Sky Watching!

The service was prompt and the laser pointer is tremendous. I can easily hit trees across a field that are 1,000 feet away. Absolutely brilliant (pun intended!).

Radian Laser

Works great. Well made and a hefty laser pointer. Beam shoots out to infinity. I would recommend this pointer.

Best Laser Pointer out there!

I have had several astro laser pointers. The Radian is by far the best. Top notch build quality, rechargeable battery with a charger, and best of all, lockable for safety. I love it!

Good tool for large groups

So far it works as advertised. Unlock the safety, check your surroundings, push the button, and direct everyones attention to what you want to show! The included instructions aren’t the best. Looks like direct to English translation so it doesn’t flow really well, but gets all the info across. The only other minor downside is the packing isn’t the best. The foam is pretty cheap and not cut well to hold the included items. I’ve only had it a couple weeks so I can’t speak to longevity. However, if you have a need for something like this and don’t want a toy, it will perform well.

Super useful and hard to find.

This is super useful for group work. I have had one of these before. I thought they were illegal in the U.S. Got my last one in Singapore, and the batteries leaked on an airplane later, This is a super useful tool for groups of people that are looking at the sky at night, so you can show them where to look.
