635 Vs 660nm glasses very intersting

[midias]

OK here is my 253mw 635nm diode Vs 253mw 660nm LOC

OK so we all know these

I noticed with my 635nm laser I could barely see the dot but I remembered that with my LOC I could see it fairly well even if after my glasses it was less than 5mw on my LPM.

After testing with some different lasers I learned 635nm does not pass through the glasses well. Check this picture out. Which one looks like 635 to you.

The weak dot is 635 nm interesting this is yes (yoda)

Wow, I didn't expect that kind of (non) filtering from a blue pair like that.
