Mirrors & 18mm Lens Upgrade Bundle for K40 Laser Cutter

Improve your machine’s performance with this high quality replacement ZnSe Lens and Molybdenum (MO) Mirrors.

This bundle includes:

3 * 20mm Molybdenum Mirrors. We chose these because even though they are slightly less reflective than SI Mirrors they can withstand more abuse.

1 * 18mm size with 50.8mm focal length which is for an upgraded head like the LightObject Air Assist. If you have a stock machine you probably need the bundle with 12mm lens. Please measure the old lens or lens holder before ordering!

This contains 3 mirrors and 1 lens.
