ZnSe has been made by means of import CVD from USA, and this material has low absorbance. The
lens can can withstand high power density and the surface coating is solid , not easy to fall off and wi
pe-resistant. After AR-coating has been coated on double-
side of imported ZnSe, the transmissivity of the wavelength 10.6um, which is commonly used in CO2 l
aser 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 sp
ot diameter in the case of the same focal length. We can respectively design and produce the product
s according to different requirements of the customers for focus length, rear focus length, lens apertur
e, the diameter of the incident ray and so on.
Laser Focus Lens 19mm FL50.8mm
Z&G corporation manufacturing laser focus lenses all adopt the U.S.A. imported CVD ZnSe. Imported CVDZnSe has double-sided semipermeable films, It can decrease or eliminate the reflective light from lens, prisms, etc.
Our focus lenses have advantages over than those of others, such as low material absorption rate enduring high power density, firm surface membrane and resistant to wipe. In CO2 laser industry working band 10.6 um, our lenses are commonly used through rate of 99.8%.
