Double Convex Cylindrical Lens
The biconvex cylindrical lens is a specialized lens that combines the characteristics of both a biconvex lens and a cylindrical lens. This type of lens exhibits biconvex properties in both principal axial directions, meaning it has a longer focal length in the central region and a shorter focal length at the edges. It is primarily used for converging light from a point source or for transmitting images to other optical systems.

Meniscus Cylindrical Lens
The meniscus cylindrical lens is a special kind of lens having a concave surface on one side and a convex surface on the other. This design makes the beam ineffective in the vertical plane, but in the horizontal plane can make the beam converge or diverge to a plane. The main function of a meniscus cylindrical lens is to correct visual aberrations by converting transmitted plane waves into cylindrical waves or cylindrical waves into plane waves or spherical waves.
