F-Theta lenses are specially designed for laser material processing applications. High Laser Damage Threshold AR coatings provide excellent throughput and durability. Typical focusing lenses offer an optimized focus for a single spot, however F-Theta lenses provide an optimized focus at many locations in the scan field on the workpiece. n If you do not find a standard F-Theta lens for your application, ask us about supplying a custom version. F-Theta Lenses are used in applications such as laser marking, bar code readers, laser micromachining, laser scanning, and many other laser applications in the microelectronics, semiconductor, automotive and medical industries.
