F-Theta lenses enable ultra-accurate processing of flat image fields without dynamic limitations. A short-focal-length F-Theta lens facilitates short working distances, as well as very compactly-dimensioned systems. Long focal length, on the other hand, allows the processing of large image fields without external axes. q8 lightWeb平场聚焦镜，也称场镜、f-theta聚焦镜，是一种专业的透镜系统，目的是将激光束在整个打标平面内形成均匀大小的聚焦光斑，是激光打标机的最重要配件之一。场镜可分为f-theta透镜和远心透镜。 q8 periphery\u0027s

Webﬂat ﬁeld scanning lens is a specialized lens system in which the focal plane of a deﬂected laser beam is a ﬂat surface. The most common uses of ﬂat ﬁeld scan-ning lenses are: Laser Machining, Pattern Generation, Laser Writing, Engraving and Marking. Additional subclasses of scanning lenses are F-theta lenses and Telecentric lenses. WebF-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).
