F-Theta Lenses are used for laser marking, bar code reader, laser micromachining and other laser applications.

◦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).

Guide	Transmittance value is a representative value only and is not guaranteed. If you have any questions, please feel free to contact our Sales Division. We accept orders to suit customized requirements. We also fabricate laser scanning systems which combine the galvanometer mirror and fθ lens as a unit.
Remark	-
Attention	We do not recommend using fθ lens in an imaging system because it is designed for a scanning type optical system. Please position the incident pupil of the fθ lens beam into the scanning system (galvanometer mirror). If the incident pupil is not in position of the beam scanning system, the optimum focusing spot cannot be achieved because of increased aberration.
