Crystal cylindrical lens
Crystal cylindrical lens
Crystal cylindrical lenses are made of special optical crystal materials such as YAG, sapphire, zinc selenide (ZnSe) and calcium fluoride (CaF2). Compared with ordinary optical glass, crystal materials feature a higher laser damage threshold, unique transmission bands and excellent thermal stability, making them the ideal choice for high-power laser systems, deep ultraviolet and far-infrared optical systems. Benchu Optoelectronics has extensive experience in processing crystal materials. Strict quality control is implemented throughout the whole process, including crystal orientation verification, cutting positioning, precision grinding and polishing, to ensure the optical axis accuracy and surface figure quality of crystal components meet the requirements of high-end optical systems.
