TPO Green Laser Pointer

The 4 to 5 mW Green Laser Pointer by TPO:

The TOP 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 4 mW, which is a guarantee you will not find on most comparable priced green lasers. The price and performance of the TPO 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 532 nm green laser is 30 times brighter and much more sensitive to the human eye than a 670 nm red laser with comparable power output. Therefore, our Green Laser Pointer will be much easier to see than a red laser.

United States

Unimpressed and Disappointed

The laser pointer is inconsistent, at best. The connection is loose, the batteries rattle around in the pointer, and the laser itself is very weak. Unimpressed and disappointed in the quality of the item.


Great laser

At first i ******* the end very tight and had some lack of brightness. But if you just unscrew it a little bit it works great. Very powerfull. Helps me a lot to aim towards my targets.

Unreliable but fixable

A great laser at first but it cut in and out and would sometimes dim. Wadding up some tin foil and stuffing it at the far end below the batteries has helped a lot to make it bright constantly.


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.
