Cylindrical Lenses

Cylindrical lenses are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism, tretching a point of light into a line, they are widely used in bar code scanning, projection optics systems, laser measurement systems and holography.

Cylindrical lenses are available in either plano-concave or plano-convex configurations from FOCtek, Plano-concave lenses ha... Read more...

Similar to a Plano-Convex lens in profile, but only as a cylinder instead of a sphere, this cylindrical lens focuses light only in one dimension. It can also transform a point image into a line image or charging the height of an image without affecting its width. There are two circumference shapes, rectangular and circular. Read more...

Lenses have many applications ranging from the simple collection of the scanning of laser beams to precise imaging and image transfer. CRYSTECH provide these lenses for different application. Read more...

As the name suggests, a cylindrical lens is an optical lens with a cylindrical or semi-cylindrical shape. Like a spherical lens, a cylindrical lens has one curved and one flat side. Unlike a spherical lens, however, cylindrical lenses aren’t fully symmetrical — the orientation of a cylindrical lens affects how it transmits light. Read more...

A cylindrical lens is typically used to focus, condense or expand incoming light. A cylindrical lens has one cylindrical surface, causing light to be focused in a single dimension or axis. It can also be used to expand the output of a laser diode into a symmetrical beam. Read more...
