Diameter:12mm/15mm/18mm/19.05mm/20mm

Focal: F38.1mm/F50.8/F63.5/F76.2/F95.2/F101.6/F127mm

CVD ZnSe material, with a transmittance of nearly 99.8% in the 10.6 μ m CO2 laser, efficiently transmits laser energy and reduces energy loss

The focal length of the lens can be controlled within ± 1%, which can accurately focus the laser on a specific focal point, forming a small and energy concentrated spot
