Just received few days ago this IR 808nm 220mW laser torch /adjustable/burning from O-like.
To my surprise, the dot is quite visible while focused at a short range. At a range of one meter it is barely visible and further more it's invisible.
My quesion is, can anyone here who owns an IR laser, report what its wavelengh and if it is visible?
For instance, is 980nm visible? 1064nm? etc.
I want to know, from people's experience, what is the highest wavelength that is visible?
TIA
