Take out the battery and look into the aperture. Do you see anything blue or green? If so, it has an IR filter.This is the laser I purposely brought as a cheap green laser pointer alternative.

It takes a 18650 and should output around 100-150mW. I am not sure whether or not it has a IR filter.
So it's cheap but not shitty cheap right? Haha

Members seem to agree to buy 2 of these ebay cheapies as that it always seems 1 is way more powerful than the other and has the potential to last.So it's cheap but not shitty cheap right? Haha
The amount of IR radiation that is colimated from the DPSS 532nm green lasers has been highly over-hyped. It is a small fraction of the overall power and is not collimated, so it disperses as the distance from the laser increases. An IR filter is nice, but in powers of 100 mW, unnecessary.
I do but then the price goes up too. For quality and reliability, you have to expect to pay a bit more. I could happily show you a cheap Chinese "5000mW" :crackup: pointer that puts out 100mW+, but the quality is nothing like what you will get from a professional company.
So I bought the laser you recommended and it is exactly what I'm looking for it is awesome I love it the only thing is that it will be super bright at first and even after the recommended duty cycle and letting it cool down it becomes not as bright almost like the batteries are dead after like 10 min if that is this normal? Any advice would help I'm just not sure the batteries should be dying even with the laser output being what it is
What one did you buy? This one? https://www.aliexpress.com/item/Hig...2687346586.html?spm=2114.40010208.4.73.PhQvjT
Are you using good alkaline batteries? It could be that if you are using carbon batteries they might be discharging after this amount of time.
