12mm Dia ZnSe Focus Lens for CO2 Laser Engraver/Cutter Cutting Machine FL 50.8mm/2"

Specification:
Type: CO2 Laser Lens Color: Yellow Material:ZnSe Diameter: 12mm Thickness: 2mm Wavelength:10.6um Focal Length: 50.8mm
Feature: - ZnSe is used for optical windows, lenses, mirrors, prisms and optical blanks, plates, disks, sheets, slabs particularly for infrared applications. - Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined. - To obtain superior transmittance, ZnSe crystals are grown by Chemical Vapor Deposition process. Zinc Selenide is polycrystalline material, demonstrates superior CO2 laser transmittance and is employed in the transmission optical components used in CO2 laser processing.
Package: 1 xZnSe Focus Lens
