Optical lens supplier 3L-Systems offers design, processing, and coating services for various types of cylindrical lenses
- CYLINDRICAL LENSES
-
Cylindrical lenses are used as laser line generators, for adjusting image height, or for correcting astigmatism in imaging systems.
They can also be manufactured from materials suitable for anti-reflective coating like BK7, UV fused silica, and CaF2.
