A plano concave lens has one flat surface and one concave spherical surface. Its center is thin and its edges are thick. With a negative focal length (f<0), it is a negative or diverging lens. It converts a parallel beam into diverging rays that appear to originate from a virtual focus F on the incident side; the rays do not actually converge there. The concave surface bends rays outward and produces spherical aberration opposite to that of a positive lens, allowing compensation of positive spherical aberration elsewhere in a system. The lens itself generates negative spherical aberration. When the object and image conjugate distances differ by more than 5×, orienting the plano concave side toward the longer conjugate minimizes residual spherical aberration.
