Lens and Mirror Cleaning and Inspection
The RayJet lens is the most delicate part of the machine. It has a relatively soft Zinc Selenide (ZnSe)
Lens, which is vulnerable to scratches from cleaning with dust on the lens, scraping, drop or thermal
shock. Trotec Lenses are manufactured by
handling page on their website
http://www.iiviinfrared.com/resources/optics_handling_cleaning.html
For a comprehensive overview of cleaning a ZnSe lens, check out the ULO Optics
.
The RayJet can take ether 1.5 inch or 2 inch lenses. We have been supplied with two types of lens -
one fits on top of the lens holding nut (2 inch lens - black ), the other below (1.5 inch lens -red). The
current lens is a 2 inch top mounted.
The mirror located in the lens housing is much more robust, but still requires delicate handling.
