for thermal expansion and should be tightened and then loosened by ½ turn. The mirrors
used are designed to give 99.9% reflectivity and are coated with an abrasion resistant
material for safe and easy cleaning. (Refer to Optics Cleaning Instructions)
Focusing lens
The 2000L series system standard configuration includes a 5”FL lens as a default. A
2.5”FL lens is supplied as an option and should be requested on the initial order but can
be retrofitted in the field at a later date. The 5”FL lens is a very good general-purpose
lens that gives a focus range of approximately 0.09” with a spot size of 0.005-0.007” in
diameter. The 2.5”FL lens is generally used for faster cut speeds in thin materials, metal
processing, or to achieve higher resolution on raster images. This lens has a focus range
of approximately 0.05-0.06” and a spot size of 0.003-0.006”. The lens used in the
MultiCam are made from ZnSe and proper cleaning (Refer to Optics Cleaning
Instructions), handling, and disposal (Handling broken/burned lens document) should be
followed.

Definitions:
Near/far field:
Near field refers to the location that is closest to the source of adjustment.
Far field refers to the location that is farthest from the source of adjustment.
