Hello all,
It's been quite a while since I've posted here. Anyway, I am trying to decide between a 1.1W 450nm from Fast Tech (it's advertised as being b/w 1W and 2W, but a YouTube video I found showed it reaching 1.1W), or a 100+ mW green laser.
I have no intention of using this to burn stuff or to point in random directions, I am using this solely for astronomy reasons with my telescope, like pointing at stars and different points in the sky, etc. And don't worry, every astronomer with half a brain knows to watch out for planes.
I checked the relative brightnesses using that calculator website that floats around the forums, and a 1.1W 450 is equivalent to a 115mW 532.
So while I think a 1.1W 450nm would look great at an observing location, I don't want to have to worry about its capability to burn things and/or cause personal harm. While a 100mW could cause some damage, I'd still much rather have the same brightness at 1/11th the power level. In either case, I'd want to have a pair of laser glasses in case.
Personally, I've tried both name brand and New Wish-style 5mW green lasers. Those things are pathetic, IMO. The second they hit anything below 50 degree F, their power output drops, anything below 40 and they stop working altogether.
Does anyone have a suggestion for a 100+mW green laser that is accurately spec'd and wont crap out in the cold?
