WebThe F-Theta JENar ® lenses are suitable for uses in micromaterial processing, especially for microstructuring or for marking and labeling different materials.. The JENar ® series is used for laser wavelengths in the UV, VIS or IR range, but they are also available for wavelengths from 355 to 1080 nm. The standard lenses are produced with protective … 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.
