Home / Custom / Optical Components / Cylindrical Mirror / Plano Concave Cylindrical Lens 
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.
