                               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%.
