F-θ flat filed scanning lenses are widely used in laser applications,such as laser marking,engraving and cutting systems.F-θ lenses are capable of creating a flat field at the image plane when working together with laser source,beam expander and galvanometers.We provides F-θ flat field scanning lenses with diffraction limited performance and high damage threshold at the lower price compared to world-famous optics companies.
