Glass Collimating Lens holder for 405-532nm Violet/Blue Green Laser Coated Glass 1pcs

It fits my laser perfectly also good quality materials. Solid product!!

The media could not be loaded. This lens is a huge improvement compared to the original from my elekslaser A3, but not ideal.The good news is that it focuses down to a smaller dot size than the original.The bad news is that there's still a lot of energy getting dispersed in an hourglass shape outside of the cutting target.

My fiance bought a class IIIA blue laser for me and the focus lens crapped out almost immediately (I think it was plastic). I ordered two of these replacement lenses because I had the feeling that I was going to screw the first one up trying to get it ajusted and I was right (no fault of the product). I got the second one put in with no issue. Works exactly as it should

Had a Thor M2 knockoff with a plastic lens that melted. Common problem. This glass lens works fine as a replacement and won't melt.

I was off on my measurementBut it was a good lense

Nothing wrong with the product. Just couldn't use it.

It works perfectly.

Works great!
