M9 Laser Tube lens for 400nm-700nm 520nm Violet/Blue Red Laser Module 1PCS

It increased my lasers cutting power. Was having to do 20 passes on 3mm ply. Put this bad boy on and it went down to 7-9 passes saving me a load of time. Going to order a couple more as spares.

The collimated beam is nearly perfect and beats all the other ones I’ve bought. Very nice metal threads and beautiful glass optics. It fits 8.6mm diameter aka 9mm thread. Tested with 515nm laser

Enhanced my blue laser. I really like the length of the metal barrel/threads, gives more room for focusing.

made from glass and way better than the original lenses

The lens that came with my module made the laser look like a line, but this lens make a perfect dot, but had to buy a second because I dropped it, lol

Out of focus lens creates wider and less powerful laser. I use it in some generic Chinese 1w laser, but it might focus better in a different one. The original lens in mine did focus well, but melted when debris got on it.
