Type of Cylindrical Lenses

CYLINDRICAL LENS

CRYLIGHT is dedicated to manufacturing high precision cylindrical lens from rapid prototyping to volume production. We provide these lenses with the material of BK7, fused silica, and other glass raw material. CRYLIGHT own the top coating expert team and the advanced coating machines in China. Our precision coating centers combine state-of-the-art deposition capabilities to achieve the most wide-ranging and demanding coating designs. If our standard coatings described in this chapter can not meet your requirements, our  engineers will help you with a special coating design.

 

A cylindrical lens is a lens that focuses light on a line instead of a point, like a spherical lens. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it into a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line and leaves it unaltered in the direction parallel to it (in the tangent plane). In a light sheet microscope, a cylindrical lens is placed in front of the illumination objective to create the light sheet used for imaging. Cylindrical lenses focus or expand light in one axis only. They can be used to focus light into a thin line in optical metrology, laser scanning, spectroscopic, laser diode, acousto-optic, and optical processor applications. They can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical lenses are widely used in telecom applications like WSS, 40G/100G modules and laser applications like pump laser modules.
