Product Details
Cylindrical 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. Cylindrical lenses are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.
Opticreate provides achromatic cylindrical lens, plane-convex cylindrical lens and plane-concave cylindrical lens, adopts special technology to ensure the center deviation accuracy, it could be controlled within 5μm, the shape of cylindrical lens could be circular, rectangular ect. We also provided cylindrical lens with reflection or anti-reflection coating.
