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
