Cylindrical Lens

Cylindrical Lens
Cylindrical lens is used to provide focusing power in one section only. For illumination or detection of light from line sources. Also used to anamorphic compression of beams and images. Especially widely used to anamorphic compression of LD (laser diode) output beam. Our cylindrical lens include fused silica cylindrical lens, CaF2 cylindrical lens, ZnSe cylindrical lens, ZnS cylindrical lens.
