OPT Green Laser Pointer
  • The OPT Green Laser Pointer has an output of 4 to 5mW, which is far better than most other green lasers on the market!

  • Competing lasers are LESS THAN 5mW and are typically in the 2mW to 3 mW range!
  • The OPT Green Laser Pointer works as a tool for business presentations and similar "pointing" needs. 532nm green laser is 30 times brighter than a 670nm red laser.
  • Astronomy OPT Green Laser Pointer beam can travel up to 10,000 feet in the darkness!



OPT 4 - 5mW Green Laser Pointer

The OPT Green Laser is new and improved, with a higher output and better quality level than our prior laser. Our astronomy green laser is guaranteed to be at least 4mW, which is a guarantee you will not find on most comparable priced green lasers. The price and performance of the OPT green laser is among the best on the market.

This green laser pointer is a continuous output diode-pumped green laser. It can be used for pointing to an array of desired targets, such as stars (makes a great finder!) and images on projection screens or video monitors. Our green laser pointer travels as far as 10,000 feet in darkness! A 532nm green laser is 30 times brighter and much more sensitive to the human eye than a 670nm red laser with comparable power output. Therefore, our Green Laser Pointer will be much easier to see than a red laser.

Works Great
Finally got a chance to use my opt laser. Worked beautifully. I've never used any other brand, but this seems like it has perfect specifications. I'd say I have above average skies at my home, not an over abundance of light pollution either. I was able to easily see the laser, straight on and from the side. When I showed my mother she was quite shocked, as was I, because I didn't expect it to be this bright. But this is within the rules, and makes using it that much better. I like the fact that it takes triple A's, instead of an uncommon watch type battery. I'd give the build 4/5 stars, it feels better in your hand once you add the battery weight though. I would think as long as one is careful with it, it should last awhile. I'll add here that the button does NOT have a lock, this is fine with me but others might not be OK with it. I can't speak to it's ability in colder weather since I was observing in a 60° climate with no dew. This will be my next test, but there are ways around this ( laser heater ) if it does have trouble. I would recommend this pointer. And if something were to happen to it I would purchase it again. Overall its a definite 5/5 for me especially when you take the low price into consideration.

Very good pointer
After researching a lot of different laser pointers I decided to get this OPT model. It's well made and very solid. My biggest concern was whether it would be bright enough (I had looked at some >5mw), and the answer is Yes - even in a fairly bright moon lit sky I had no problems pointing out stars and other astronomical objects. Overall, great pointer at a good price.

Good quality and value
I purchased this after trying a $6 laser at Amazon. That one only worked for one minute before it faded and failed.

This one from OPT was delivered in a timely fashion, and came with batteries that worked as well as a simple instruction sheet.

This laser worked right away, and kept on working. It seems to have the identical design to the one that didn't, but it must have better components.

The laser is bright, and does not fade.

Using it at a star party it was very useful pointing out constellations, the beam easily visible once it was dark enough to see 2nd magnitude stars.

Unlike the product photo at OPT, this pointer is a 'brushed silver metallic finish.
