1. Strict dimension control, process Cylindrical Lens of diversified specifications and radius according to drawing.
2. Options of material: Optical Glasses，Laser Crystal，Fused Silica，Radiation Resistant Glasses，IR & UV Materials，Metal Materials.

Combined with a Plano-convex Lens, Plano-concave Cylindrical Lens can be used to shape an Elliptical Beam of a Semiconductor Laser into a circular beam. It also can be used in Projection System, Imaging System, Optical Instrument and Laser Measuring System. Boxin selects the preferred material, process and Coating in according to cutomers’s requirement.
