The laser focus lens features CVD ZnSe imported from America, boasting low material absorption rate, excellent high-power density endurance, firm surface membrane, and great scratch resistance. The imported CVD ZnSe double-side antireflection film is mainly used to decrease or eliminate the reflective lights from optical lens, prisms, plane mirrors, etc. so as to increase light penetration and decline or eliminate stray lights. To adapt to increasingly expanded applications, various antireflection films are developed, like single-wavelength antireflection film, dual-wavelength antireflection film, bandwidth antireflection film, super wide bandwidth antireflection film, dual-waveband antireflection film, etc. In the common working band (10.6 um) of CO2 laser industry, the transmittance of the CO2 laser focus lens can reach stunning 99.8%. This single chip focus lens is often used as laser cutting machine focus lens, laser engraving machine focus lens, etc.

All the CVD ZnSe focus lenses with common diameters like 18mm, 19.05mm, 20mm, and 25mm are available in Eastern Laser, and we also provide trailer-made laser focus lenses with various diameters to satisfy any requirement.
