Seller Promise:
wholesaledia 20mm FL3inch co2 znse laser focusing lens
Competitive price but good quality
Ultra-low absorbing of infrared beam
Stand highest power density
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%.
