Cylindrical Lenses

We supply plano convex and plano concave cylindrical lenses, cylindrical achromats or combined biconvex lenses (spherical radii and cylindrical radii) for many different uses: in projectors and collimators, to correct astigmatism or for the beam expansion and homogenization of laser beams. It is even possible to produce special sizes with a range of CNC-produced contours.
