but is thinner at the center than at the edges. Otherwise description is similar to Plano Concave lenses.
its role is making beam converging or diverging on a plane, and that beam does`t work for the perpendicular plane (cylindrical axis) with it of the appropriate wavelength.
When used to form a positive lens assembly, the Positive Meniscus Lens can increase the NA of the system while
decreasing the total spherical aberrations. The Negative Meniscus lens is used to increase the focal length of another lens We are mainly specialized in the production of lens, prisms, mirrors, cylindrical lens, beam splitters, filters and windows and blanks and infrared Material included Znse, Germanium, ZnS, BaF2 and CaF2 etc
