Minimum Order : 1 , Pieces

F Theta Scanning Lens For CO2 Laser

F-Theta Scanning Lens is commonly used in conjunction with galvanometer scanning mirrors in laser engraving, cutting, and marking systems. The reason it being named as F-theta is due to the radial image height equals to focal length of the lens multiplied by the angle of the chief ray makes in the object space. Hence, from the image height, the distortion of the image can be calculated at each field of interest. Typically the F-theta distortion of this lens is kept less than 1% so that it produces a precise spot on the flat field on image plane.

F-Theta scanning lens - CO2 laser scanning lens
Monolithic flat field scanning lens design is applied to the use of the galvanometer scanning carbon dioxide laser scanning system, its widely used in laser drilling marking, etc
