Cylindrical Lenses

Product Information
Cylindrical lenses have a spherical radius in one direction only, where:
 

  • Close curvature tolerance are maintained (despite the product thickness)
  • High precision radii are ensured
  • Awkward glass types can machined
  • Convex radii from 1 mm to 10 mm can be produced
  • Centering accuracy in the order of 2 minutes on small rectangular lenses
  • Coating capabilities.

Applications
The main applications for cylinder lenses are in laser projection, bar code scanning, holography, optical information processing and computing.

Materials
All types of optical glass
