WebThe longitudinal distortion of the spot is caused by many spectral components that are focused with an offset on the working plane. The offset is much larger for strongly tilted ingoing beams than in the more central areas. ... F-theta lenses are designed to focus a laser beam onto a planar image plane. They are often used in a scanning system ... Webφ106mm. Screw. M85P1. F-Theta lenses convert a rotational movement of a galvanometer mirror into a linear motion on the focal plane by using distortion effects. Telecentric type is also available that can be irradiated vertically to the focusing plane. Also available for fundamental YAG laser (1064nm), harmonic lasers (266nm, 355nm, 532nm).
