Laser Tube lens Collimating Coated Glass Lens for 400nm-700nm 520nm Violet/Blue Red Laser Diode Module

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 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

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

I can get a more defined narrow beam with this lens than the stock one

made from glass and way better than the original lenses

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.
