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.
Figure 1: Plano-Convex Circular Cylinder Lens
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)
