The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The input lens presents a virtual beam focus at the output. For low expansion ratios (1.3-20 times) the Galilean telescope is most often employed due to its simplicity, small package size and low cost.

Optical Cylindrical lens PARAMETER: 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.
