Menscus cylindrical lens

  • One side of meniscus cylindrical lens is concave and the other side is convex. Its function is to make the beam converge or diverge to a plane, and the beam does not work in the vertical plane. Meniscus cylindrical mirror can convert transmitted plane wave into cylindrical wave or cylindrical wave into plane wave or spherical wave. This kind of lens can correct visual aberration. 

Moreover, the edge thickness is larger than the center thickness, which can limit the reduction of spherical aberration. It is often used to combine with another lens to form an optical system, so as to reduce the numerical aperture. It is a common element in beam expansion applications.
