Hey Guys ,
I removed three element lens from my 405nm and now I'm not sure which one goes back in . I also have a lens from a recently sadly destroyed red .
So is it the lens with blue tinge or the one with gold colour ?
I 'd really hate myself for destroying another $100 bluey
I tried to UTFSE but wouldnt accept the word ' three'

The lens with the yellow/gold hue is for the 405nm/445nm laser. The other one with the blue hue is for the red laser.
