Product description
F-Theta scan lenses keep the focused spot on a flat image plane as galvanometer mirrors steer the beam. They are essential in laser marking, engraving, and precision micromachining systems.
YC Infrared Optics supplies F-Theta optics for common industrial wavelengths including 1064 nm, 355 nm, and 10.6 μm (ZnSe designs). Scan field size, entrance pupil, and telecentricity options are selected to match the galvo and process requirements.
Mounting interfaces can follow standard housings or custom mechanical envelopes for OEM integration.
