  A plano concave cylindrical lens  is used to expand light in on-axis.  A negative concave cylindrical lens  is able to diverge collimated input light away from a line.  Plano-concave cylindrical lenses are used for one-dimensional compression of images, anamorphic beam shaping, and laser line generation. If you have the demand, please feel free to contact BRD Optical.   Descriptions Of Plano Concave Cylindrical Lens   The plano-concave cylindrical lens forms a divergent linear virtual image, which is used to control the size of the beam in one direction. The material of this lens is BK7, so it is not suitable for ultraviolet wavelengths.   The plano cylindrical lens is used in laser scanners, spectrometers, dye lasers, acousto-optics, optical processors, and other similar applications.   We use high-quality optical glass classical optics grinding, polishing processing techniques, surface accuracy of up to λ / 4, the finish may be 40/20.
