20 mm ZnSe Co2 Laser Focus Lens For Polarization Microscope
ZnSe material has been made by means of import CVD from USA, and this material has low absorbance. The les can withstand high power density and the surface coating is solid,not easy to fall off and wipe-resistant.After AR-coating has been coated on doiuble side of ZnSe, the transmissivity of the wavelength 10.6um which is commonly used Co2 laser industry, can reach 99.5%.We have optimized the design from two sides-diffraction and aberration and have developed a series of products with the minimum actual focal spot diameter the case of the same focal length.We can respectively design and produce the products according to your requirements of the focal length,diameter,flatness...
