Default Re: Searching low power blue laser

Right now I do not care what kind of technique it is, as long as it is some kind of blue. I am a beginner. Maybe someday I will have higher demands, who knows

I wrote a mail to laserbtb and asked my questions. Now waiting for response.

Thank you all for your help!

You can have a look at what a 5mW 520nm green looks like here: http://laserpointerforums.com/f45/re...er-99820.html?

445nm blue will only be approx. 10% as bright to the eye at same output power.

Hm, seems to be impossible to have a blue pointer with at least a slight beam without eye damaging power...

A 473nm 5mW will have a good visible beam in the dark. While it isn't going to be as bright as 532nm it's still visible

So, as Alex said, maybe you need to save up some bucks for this awesome wavelength.

Or you can get one laser for playing and one for a nice beam, but not eye safe - in class 3B (or even 4).
