CO2 laser engraving machine focus lens ZnSe lenses Φ 12 F=50.8mm IR
Optics
Description:
Znse is used for the optical windows , Lenses. Mirrors, prisms and
optical blanks, plates. disks, sheets , slabs particularly for
infrared application.
Znse-transparent in wide spectral range from yellow to far IR, Znse
material is a chemically inert,non-hygroscopic and highly pure
products 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.
CO2 laser focus lens is widely used in laser processing (cutting,
drilling, welding, carving, etc.) and various laser systems
