Biconvex cylindrical lenses
Biconvex cylindrical lenses feature convex cylindrical surfaces on both sides, delivering shorter focal lengths and stronger focusing performance than plano-convex designs. They are ideal for high-power laser line focusing within compact optical paths. The symmetric structure helps reduce aberrations and achieves superior image quality without additional optical elements.
