China PVD Znse Focus Lens

Focusing lenses are used to focus laser beam. The objective of focusing the laser beam is to concentrate the laser power for material processing, ZnSe lenses are widely used for CO2 laser applications because of its low absorption at infrared wavelengths as well as its visible transmission.
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.
