Optical Cylindrical Lens

A cylindrical optical lens is typically used to focus, condense or expand incoming light. A cylindrical optical lens has one cylindrical surface, causing light to be focussed in a single dimension or axis. It can also be used to expand the output of a laser diode into a symmetrical beam. Cylindrical optical lenses are technically more difficult to manufacture than spherical or flat lenses which is why Ecoptik (also known as BRD Optical) uses state-of-the-art polishing techniques alongside stringent lens assessment to manufacture each lens.

 

Cylindrical optical lenses are typically rectangular, square, or circular and of either a plano-convex or plano-concave design. The cylindrical optical lenses of Ecoptik (also known as BRD Optical) combine low wedge with high surface accuracy. As a leading optical components manufacturer, we assess the quality of each individual lens using Trioptics centration measurement and a Zygo GPI interferometer.  All Ecoptik lenses are available both uncoated or coated with a broad range of high durability, low loss AR coatings, and can be manufactured to 20-10 surface roughness.

 

Types Of Optical Cylindrical Lens

 

Plano Concave Cylindrical Lens

A plano-concave cylindrical lens is used to expand light in on-axis. A negative cylindrical lens is able to diverge collimated input light away from a line.  Plano-concave cylindrical lenses are used for one-dimensional compression of images, anamorphic beam shaping, and laser line generation.
