UV Fused Silica Optical Cylinder Lens 20mm Single Vision Lenses

Overview:

The Biconcave (Double-concave) Cylindrical Lens is generally used to utilized to enlarge light in single dimension or change the aspect ratio of the image. The double concave cylindrical lens can separate input collimated light away from a line. They are best for one-dimensional compression of images, laser line generation and anamorphic beam shaping.
