Meniscus lenses have two curved surfaces which are referred to as convex-concave lenses. Radius of curvature of both surface can be chosen independently from each other. Meniscus lenses find application in optical systems, where aberrations need to be minimized, for instance in multi lens focusing objective, where it helps to minimize focal spot of the beam. The lenses is applied in collimators. Another advantage is that meniscus design allows to make longer focal length lenses than the ones available in Plano-convex design.
