Plano-Concave Cylindrical Lens

Product Details

Cylindricallenses are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.

Opticreateprovides achromatic cylindricallens, plane-convex cylindrical lensandplane-concave cylindrical lens,adopts special technology to ensure the center deviation accuracy, itcould be controlled within 5μm, the shapeof cylindricallenscould be circular, rectangularect.We also provided with reflectionor anti-reflection coating.
