Double-concave Cylinder Lens

Cylindrical lenses have at least one surface that is formed like a portion of a cylinder.Cylindrical lenses are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism,stretching a point of light into a line.They are available in either plano-concave or plano-convex configurations. Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.

Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens. Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
