ZnSe Lens - 12mm - for K40 Laser with Stock Head

Improve your machine's performance with this high quality replacement ZnSe Lens. 

This is 12mm size with 50.8mm focal length which is the default K40 lens size and what you need for the stock head.  If you have upgraded your machine with an air assist head, you may need a different size such as 18mm. 

Please measure the old lens or lens holder before ordering!

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

This contains 1 lens.

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 Air Assist Head: ZnSe Lens - 18mm - for K40 with Some Upgraded Heads
