USA CVD Znse Focus Lens

The base material of ZnSe focus mirror is laser grade CVD zinc selenide material. The function of ZnSe focus mirror is to focus the light beam, produce the focus of high energy density to process the working substance; the design and processing accuracy is high, all systems reach the dffraction limit;the focal depth is long and the whole focal depth range is consistent wel. 

YANNTEK Focus Lens have two material：CVD ZnSe and PVD ZnSe. Focus lens shape have Meniscus lenses and Plano-convex Lenses. Meniscus lenses are deigned to minimize spherical aberration, producing a minimum focal spot size for incoming collimated light.Plano-convex Lenses, the most economical transmissive focusing elements available,

YANNTEK ZnSe Focus Lens are ideally suited for laser head treating, welding, cutting, and infrared radiation collection where spot size or image quality is not critical. They are also the economical choice in high f-number, diffraction limited systems where lens shape has virtually no effect on system performance.
