F-Theta Scan Lenses are developed for ultrafast lasers with short pulse width and high pulse energy laser applications. These lenses are made with low dispersion Fused Silica with optical design to avoid back reflection and ghost image.

Standard fused silica f-theta lenses are suitable for all high-power-laser applications like welding,cleaning, and structuring. Thermal lens, which occurs at high power laser applications and leads to afocal shift, is also minimized.
