Hello folks,
I've recently completed most rainbow(at least good enough for me) so I was thinking about venturing out into the Near-IR range of lasers just so I can have one in my possession, as every hobbyist should! :D
Now, laserbtb has some pretty neat 808nm pen styled lasers for pretty good prices. The one I am eyeing is their 5mW version(most likely more) for $26.57! I do have a few questions though, and yes, I did look in the search bar but most the questions regarding visibility for this wavelength weren't as such low powers, mostly around 100mW-300mW.
-Would 5mW of 808 be visible? At all? I don't need anything stunning but I've seen 4mW's of 405 in mid-day and could barely see the dot across my room. I've read that the human eye can actually see past the "general" 780nm end limit range of what you can see. I am not very interested in going into their next power level, 100mW as this stats entering dangerous territory, plus I'd most likely not use it other then to look at! :)
Thank you! :D
