Cylindrical lenses

Short Description:

Cylinder lenses are a type of lens that have differing radii in the X and Y axes, causing the lens to have a cylindrical or semi-cylindrical shape, and image magnification in only a single axis. Cylinder lenses are commonly used as laser line generators, or to adjust image height size or correct for astigmatism in imaging systems.

we produce cylinder optics and plane optics (cylinder lenses and mirrors) for demanding applications used in imaging and beam guidance systems.
Example areas of use are:
Field of view and distortion correction (photo/film)
Beam guidance, expansion, homogenization and astigmatic correction in laser systems (material processing: lift-off and annealing, drilling, welding, rapid and additive manufacturing)
Beam guidance, expansion and astigmatic correction (printing)
