This Class III green laser emits a tight, shimmering green beam that’s easily visible in the air.
What do you want in a laser? A bright, visible beam that disappears into the night sky! But when it comes to buying a laser pointer, you can spend hundreds of dollars to get what you want or less than $50 and hope for the best. Lasers are often overrated and over-pitched. We scoured scientific equipment distributors and researched these lasers carefully before purchasing for our store. They are 532 nm (green laser) in a durable pen-shaped aluminum alloy body. The label confirms they are Class III and rated at 1mW. Companies market these as 5mW Class III lasers.
So how bright are they? The first thing we did when these pen lasers arrived is head out of the shop and shoot a beam at a water tower located a little more than three-hundred yards away from our building. The laser painted a bright, green dot on the tower with a beam easily visible through the entire distance. At closer targets, the laser created a bright, green splash. Yes, this laser pointer is bright and worthy of the Class III designation – if not slightly more.
A Class III green laser runs cool but a higher-rated Class IIIb green laser can heat up the skin if held closely for several seconds. We tested it and think this laser pointer could be rated more accurately between Class III and Class IIIb. Of course, this means it’s too bright to be used as a laser pointer for presentations and such.
About Class III green lasers
Class III lasers requires less than 5mW to be effective. Class III green lasers are bright, but not exceptionally dangerous. According to Wikepedia, brief contact with the eye holds a low risk of damaging the retina. A Class III laser beam can travel 11,169 feet or about 2 1/2 miles.
