RONAR-SMITH ZnSe CO2 Laser Scan Lens 10.6μm 150mm Focal Length 110×110mm

F-Theta lenses are commonly used in conjunction with galvanometer scanning mirrors in laser engraving, cutting, and marking systems. Typically the F-Theta distortion of the lens is kept less than 1% so that it is able to produce a precise spot in the flat field on the image plane.
