Powell Prism Laser Line Prism Powell Lenses

26 Mar 2025

Powell prism (Powell Lens) is a specially designed aspheric optical prism, mainly used to convert Gaussian beams (such as laser beams) into linear light spots evenly distributed along a straight line. Unlike traditional cylindrical lenses or diffusers, Powell prisms can provide linear lighting with higher uniformity and stability, so they are widely used in laser processing, machine vision, biomedicine and other fields.
