◦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).
