Zinc selenide focus lens are widely used in CO2 laser process， including cutting， drilling， carving & other laser system. With the imported material， our products can withstand high power density; and the film is solid， with which the lens are resistant to wipe. Because of the double-side film， the filterability of the light (the wavelength is 10.6μm) can reach 99%.
