I got one of these today, and I don't think it works. I soldered it to a module board that used to support a 25mw 780nm laser, but has a pot on it, and in addition, I added an led in paralell, to check the circuit. I'm using a gen 1 night vision scope to check it, and it doesnt seem to do anything. I was wondering if anyone had an idea of what the spectral sensitivity of night vision is? I researched IR laser sights (this is how I came crashing into this unexpected new offshoot hobby, I wanted one, and whomever sets the pricetags on those is on drugs!, and just like that, bang, I'm building lasers, now) the ones that say, say they like the 830nm band, and I didn't like the 780nm band, becasue there was too much bleedover into the visable spectrum (I could see it), I should think 808nm would therefore be a bracketed range. However, this idea was shot down by the 25mw 780nm module that sacrificed it's pcb, anyway, since 25mw hurt my poor nightscope, 5mw would be more than sufficient, I think, but I had big dreams of burning bugs, for this diode, I'm disappointed.
