What is a meniscus lens
Meniscus cylinder Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.
Description Of Meniscus Cylindrical Lens
It is a lens that one surface is the convex shape, another surface is concave with a cylindrical shape, its role is making beam converging or diverging on a plane, and that beam doesnt work for the perpendicular plane(cylindrical axis) with it. A cylindrical lens is used in turning a transmitted plane wave into a cylindrical wave, or turn an original cylindrical wave into a plane wave or spherical wave, such a kind of lens can correct ocular astigmation.

PARAMETER: Cylinder Lenses are typically used to focus incoming light to a line, or to change the aspect ratio of an image. Cylindrical Lenses have a single cylindrical surface that causes incoming light to be focused in only a single dimension, stretching the image. Cylinder Lenses are available with positive or negative focal lengths, ideal for laser line generation or anamorphic beam shaping to circularize laser outputs.
