FF1064 160/3E/M85 F-Theta Lenses, also called Scan Lenses, are a particular type of lenses utilized in combination with XY galvanometer scanners or polygon scanners. They are utilized in a multitude of fields, such as industrial material processing and medical and biotechnological applications. It's very important to note that the lens performance is very dependent of the design and quality of its optical components. Compared to standard lenses, where the laser beam is focused on a spherical surface, f-theta lenses provide a plane focusing surface and constant spot size over the entire XY image plane. OPTO5 F-Theta lenses meet the standard requirements of the laser marking world, combining the most popular focal lengths and mounts with precise spot positioning and uniform beam quality over the whole engraving/etching field. Our flagship F-Theta lens is designed for the nominal 1064 nm laser wavelength. A 532 nm multilayer coated version is also available.
