φ20mm FL=190.5mm IR Optics Znse focus lens CO2 Laser cutting focus lens
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
