At least one of the faces represents the curvature of a sphere segment Therefore, these lenses are also known as spherical lenses (spheros, Greek=sphere). Biconvex lenses are convex on both sides. They permit less distortion at higher magnifications than planoconvex lenses. An aplanatic lens system consists of 2 planoconvex lenses, whose flat faces both are directed outwards. This allows a sharp-edged image free of distortion. 210
