Plano Concave lenses

- Options of material: Optical Glasses,Laser Crystal,Fused Silica,Radiation Resistant Glasses,IR & UV Materials,Metal Materials
- Strict Dimension Control Standard
- Customized Coating
A Plano-concave lens consists of a plane and a concave spherical surface that generate negative spherical aberration. It’s often used in systems to expand the beam or increase the focal length to balance the deviation of other lenses. It can be used in Camera Systems, Projection Systems, Imaging Systems, Optical Viewfinders, Laser Measurement Systems. Boxin selects the preferred material, processing and coating in according to meet customer’s requirements. For details, please contact our sales team.
