F-Theta Flat-Field Scanning Lens FTS0330
F-Theta flat-field scan lenses are standard components in galvanometer-based laser marking, cutting, and engraving systems. Their multi-element, air-spaced design is optimized to provide a flat field at the image plane. Each element in Youguang Technology's F-Theta flat-field scan lenses has a high-power antireflection coating, and the outer mount has a standard M85x1 interface.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
