Product Description

Cylindrical Lens has a curvature on one dimension and designed for focusing light source into one-dimensional shape. In other words, to change the way of the light source in an optical system and turns it to a linear light source. The cylindrical lens can be used to correct astigmatism of an optical system. It is widely used in high precision measuring instruments and devices such as the high-power and long distance linear interferometer. Cylindrical lens is also often used in Synchrotron Radiation Beamlines, Barcode Scanning and High-power Laser system etc. Boxin supplies cylindrical lenses in a various types of materials in order to meet customer’s demands, including Optical Glasses, Laser Crystal, Fused Silica, Radiation Resistant Glasses, IR & UV Materials and Metal Materials, e.g., SiO₂,CaF₂,BaF₂,ZnSe and ZnS etc.
