F-Theta Scan Lens

The F-theta Scan Lens can provide a small focused spot size within a large field of view and minimize distortion, thereby achieving high-speed operation in applications such as marking, engraving, welding, and PCB drilling.

Product Description and Features:

Our F-theta Scan Lens uses imported ZnSe material and is designed and produced according to the needs and characteristics of the CO2 laser marking market. The principle is to use the special dispersion properties of the material to eliminate chromatic aberration and correct aberration through the optical system, while reducing the volume and weight of the system. Aberration analysis shows that the system has excellent chromatic aberration, field curvature, and F-theta error characteristics. In particular, the output spot is small (diffraction limit) and uniform, with excellent scanning characteristics, meeting the actual needs of high-speed, high-precision laser marking machines.
