Cylindrical Lens

Cylinder Lenses 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,These cylindrical lenses are designed for applications requiring one-dimensional shaping of a light source.

We are offered plano-concave or plano-convex, bi-convex, biconcave, achromatic, triplet lens, rod lenswith N-BK7 glass, UV fused silica, or CaF2, Sapphire, and coating or not upon request
