Cylindrical Lenses

Cylindrical lenses are available in either plano-concave or plano-convex configurations from FOCtek, Plano-concave lenses have a negative focal length and are used for image reduction or to spread light Plano-convex lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.

Recall that the visible wavelength ranges are: 430 to 490 nm = blue; 490 to 530 nm = green; 530 to 580 nm = yellow; 580 to 630 nm = orange and 630 to 700 nm = red. 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...

Double Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths. Uni-Optics offers Double Concave lenses with a variety of coating options. Read more...

They are widely used in bar code scanning, projection optics systems, laser measurement systems and holography. Read more...

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. 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...
