A Lens is a Transmissive Optical Device that affects the focus of a light beam through refraction. A simple Lens consists of a single piece of material, while a compound Lens consists of several simple lenses (elements), usually along a common axis. Lenses are made from transparent materials such as glass, polymers etc which are ground and polished to a desired shape. A Lens can focus light to form an image.



It focuses light in only one dimension. Similar to a PCX Lens in profile, but is a portion of a cylinder instead of a sphere. Cylinder lenses can transform a point of light into a line image.

Note: For Rectangular Lenses, radius of curvature is parallel to first dimension.

A cylindrical lens can be used in a broad range industrial, research and OEM applications. Typically, they are used in spectroscopy, holography, laser scanning optical metrology, acousto-optic and laser diode applications.

Cylindrical lensCylindrical-LensUsed to provide focusing power in one section only. For illumination or detection of light from line sources. Also used for anamorphic compression of beams and images.BK7/ Fused Silica/CaF2 /other optical glass
