Plano-Concave Lens
Plano-concave lenses diverge a collimated beam from a virtual focus and are commonly used in Galilean-type beam expanders. Plano-Concave lenses have a negative focal length and negative spherical aberration, which can be used to balance out aberrations of other lenses in the system.
