Arrow not a dumb question

so i ordered a 445nm module kit for aixiz and it came with 2 lenses. One appears to be plastic and short and the other is metal and about twice as long...my question is what is the difference (other than the obvious) of them?

One is acrylic (small black on). Other one is some sort of glass lens and will probably give you more output.

Is there a color or hue to the longer lens. Hopefully when you look at it at an angle it will have a slight yellowish hue. If its clear I would suggests ordering one one their 445 3 element lens. It's not the Cadillac, but will serve you well.

The smaller plastic one is most likely the standard AixiZ acrylic lens. Don't use that with your 445nm build! I smoked my first 445nm laser by using an AixiZ acrylic lens. The lens burned up from the high output and ruined my precious laser diode.

Default Re: not a dumb question

Did your len/s also come with a chrome part that has splines on the Outside dia? This is to help focus your lens at different distances. I hand-tightened mine so that it would rotate the lens in and out of the module, then made a larger focal ring adapter so I didn't burn my fingers. People here make them for sale so check the appopriate area for that. Also don't freak like I did if you have a large blue blob instead of a dot. I had screwed my lens all the way in. Needed to back it off a little thus focusing it. (Same thing as a magnifying glass).

You should get a lower divergence with the glass one aswell.
