7-Day Rapid Prototyping!
Plano-Concave Cylindrical Lenses
Plano-concave cylindrical lenses have one flat surface and one concave cylindrical surface, mainly used for uniaxial divergence and expansion of laser beams, and serve as key components in laser diode beam shaping and astigmatism correction systems. When matched with plano-convex cylindrical lenses, they can form variable-magnification laser beam shaping systems for precise beam width adjustment. Benchu Optoelectronics plano-concave cylindrical lenses feature stable precision and consistent manufacturing quality, suitable for mass production projects requiring strict batch repeatability.
