Coupletech supplies high quality plano convex cylindrical lenses and plano concave cylindrical lens. Optical Lenses Cylindrical lenses as a kind of Laser Component are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism, tretching a point of light into a line, Plano Convex and Plano Concave Cylindrical Lenses are widely used in bar code scanning, projection optics systems, laser projection, laser measurement systems and holography.
A cylindrical lens is demonstrated using two planar substrates and a homogeneous liquid crystal (LC) layer. The top substrate has slit electrodes on its outer surface and the bottom has a transparent electrode on its inner surface. An applied voltage across the cell induces a cylindrical-like gradient refractive index within the LC layer which causes light to focus. The focal length is tunable by the applied voltage. Such a cylindrical lens can be easily fabricated with wide aperture size. Cylindrical lenses have a spherical radius in one direction.
This kind of Optical Elements enables the light to be focused in one axis. A point of light can thus be stretched into a single line. Coupletech are able to offer other kind of Optical Element, which has included Optical Filters, Beamsplitter, Optical Windows, Optical Mirrors, optical prism, and so on.
