タイトルまたは説明

Positive Meniscus Lenses And Negative Meniscus Lenses

The Positive Meniscus Lenses are a convex-concave lens, but it is thicker at the center than at the edges. They are felt polished and are used universally in the ophthalmic industry where convention dictates that lens power be specified in Diopters.

The Negative Meniscus Lenses are a convex-concave lens, but it is thinner at the center than at the edges. Otherwise description is similar to Plano Concave lenses.
1. What's the advantages of using Meniscus Lenses?
It produce a smaller focal point and fewer aberrations than a standard plano-convex lens and enhance image quality.
2. What is Meniscus Lens?
Meniscus lenses have two curved surfaces,convex on one side and concave on the other side. It is thicker at the center than at the edges. When a meniscus lens is combined with another lens, the focal length is shortened and the numerical aperture of the system is increased.
3. What's the applications of Meniscus Lens?
Negative meniscus lenses are often used for Infrared Application. These lenses are used as an alternative to other negative lenses with a greater curvature on the concave side and a smaller curvature on the convex side.
