Cylindrical Lenses - Cylindrical Optics

BERLINER GLAS manufactures high precision cylindrical optics in a variety of sizes and shapes for applications such as in line projectors, collimators, astigmatism correction units, beam expanders or for homogenization of laser beams.

 

The optics are offered as:

 

  • plano convex and plano concave cylindrical lenses
  • cylindrical achromats
  • rods
  • tubes
  • mirrors
  • combined biconvex lenses (spherical radii and cylindrical radii).

 

It is possible to produce special sizes with a range of CNC-produced contours.
