Cylinder Lenses are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. Cylinder Lenses are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.
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.
