Product Description:

A cylindrical lens is typically used to focus, condense or expand incoming light.  A cylindrical 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 lenses are technically more difficult to manufacture than spherical or flat lenses which is why our company use state-of-the-art polishing techniques alongside stringent lens assessment to manufacture each lens.

A cylindrical lens is typically rectangular, square or circular and of either a plano-convex or plano-concave design. ULO’s cylindrical lenses combine low wedge with high surface accuracy. We assess the quality of each individual lens using Trioptics centration measurement and a Zygo GPI interferometer.  All our lenses are available both uncoated or coated with a broad range of high durability, low loss AR coatings and can manufactured to 20-10 surface roughness.

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.
