Audited Supplier F-theta scan lens is used in conjunction with XY galvanometer scanner and beam expander to form a two
dimensions scanning system. The scan lens is optimized to provide a flat field image with diffraction-limited
spot size in micron scale over the entire scan field. The image field height is almost directly proportional to
the scan angle. Typically, the linearity f-theta distortion is kept less than 1% without software correction to
ensure minimal distortion. High transmissive AR coating is coated onto the lens elements surface to ensure
minimal power loss and hence increase the throughput. The scan lenses are designed with a industrial
standard M85x1 mount threading to facilitate lens installation into laser machine. To accommodate different
standard mount thread, mount adaptors are available for ease of conversion. Most of our products are RoHS
compliant unless otherwise stated.
Aperture Stop is set at center point of X-Y mirror in case of two-axis scanning system.
