ECOPTIK (CHANGCHUN) LTD Cylinder Lens / Optical Lenses

A cylindrical lens is typically used to focus, condense or expand incoming light. A cylindrical lens has one cylindrical surface, causing light to be focused 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 BRD Optical 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. BRD Optical's cylindrical lenses combine low wedge with high surface accuracy. As one of the best optical manufacturers, we assess the quality of each individual lens using Trioptics centration measurement and a Zygo GPI interferometer. All BRD Optical 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.
