Meniscus lens is a lens which has two spherical curved surfaces, convex on one side and concave on the other side.It is thicker at the center than at the edges. The lens provides a smaller beam diameter in order to reduce the beam waste and spherical aberration. When a meniscus lens is combined with another lens, the focal length is shortened and the numerical aperture of the system is increased. This reduces the image distortion and increases image resolution.
