20mm Molybdenum (MO) Mirror

Improve your machine’s performance with this high quality replacement Molybdenum (MO) Mirror.

We chose these because even though they are slightly less reflective than SI Mirrors they can withstand more abuse.

Perfect size for the K40 Laser Cutter and any other machine that takes 20mm mirrors.

A laser cutter will typically contain 3 mirrors and 1 focus lens.

This contains 1 mirror.  A laser cutter usually requires 3 mirrors to do a full optics upgrade.

Here’s what you need in order to do a full optics replacement/ upgrade:

3 * 20mm Mirrors:  Molybdenum (MO) Mirror – 20 MM – for K40 Laser

AND

1 * 12mm Lens if you have the stock K40 head: ZnSe Lens – 12mm – for K40 Laser with Stock Head

OR POSSIBLY (MEASURE YOUR LENS/ LENS HOLDER!)

1 * 18mm Lens if you have an upgraded head like the LightObject Air Assist: ZnSe Lens – 18mm – for K40 with Some Upgraded Heads
