Cylindrical Lens
Description
Cylindrical lenses used to provide focusing power in one sectiononly. 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 These lenses are made of BK7, fused silica and CaF2. Special focusing systems can be designed by our engineers upon request.
