The meniscus cylindrical lens has a concave surface on one side and a convex surface on the other.
The meniscus cylindrical lens has a cylindrical surface, which enables the incident light to focus on a certain dimension and stretch the image. The focal length of meniscus cylindrical lens can be positive or negative, which is suitable for laser line generation or deformed beam shaping. The meniscus cylindrical mirror can convert transmitted plane waves into cylindrical waves or convert cylindrical waves into plane or spherical waves, and this type of lens can correct visual aberrations.
