A plano-concave cylindrical lens is used to expand light in on-axis. A negative 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.
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. We can also be processed according to customer demand layers.
