Germanium Lens Specification
2 fringe @632.8nm/customized
1 fringe @632.8nm/customized
windows are used in optical systems to seqarate the environment of one part of the system from another. For CO2-lasers ,ICC offers windows produced from
-AR coated windows
-Combined coated windows
Utilized for CO2-laser-based heatreating, welding, cutting, drilling, and marking apparatuses.
Baises the plane-convex and meniscus lens shapes already mentioned, ICC supplies biconvex and cylindrical lenses. Customer-made lenses are manufactured upon request.
Zinc selenide, Gallium Arsenide, and Patassium Chloride can be used for production of lenses. Standard ZnSe and GaAs lenses are offered are offered with both surfaces AR coating at 10.6um.KCL lenses are supplied uncoated.
