Meniscus Lenses are concave-convex lenses that contain both positive and negative meniscus lenses. The Positive meniscus lenses are thicker in the middle than at the edges, allowing light to converge, and are designed to reduce tertiary spherical aberration. When they are used to converge a collimated beam, the convex side should ...

CONVEX AND CONCAVE MENISCUS LENSES MCX - MCC
Tecnottica Consonni
Meniscus lenses are divided into positive and negative: both are distinguished from other lenses since, by definition, have a convex surface and a concave surface. These lenses are often used to shorten or lengthen the focal length of an optical system that already exists. In addition, meniscus lenses can be properly designed so that ...

Positive meniscus (convex-concave) lenses, with center thickness bigger, are designed to minimize spherical aberration. When used in combination with another lens, a positive meniscus lens will shorten the focal length and increase the numerical aperture (NA) of the system without introducing significant spherical aberration. When ...

Negative meniscus (convex-concave) lenses, with center thickness smaller, are designed to minimize spherical aberration in optical systems. When used in combination with another lens, a negative meniscus lens will increase the focal length and decrease the numerical aperture (NA) of the system. When used to diverge light, as shown in ...

Did You know?

Meniscus lenses have a combination of concave on one side and convex on the other side surfaces. They are also known as convex-concave lenses. Depending on the relative sharpness of the curvature between the outer and inner surfaces these lenses can be positive or negative. The key properties of these lenses are the minimized spherical aberrations and increased numerical aperture, which makes them critical for optical corrective applications such as optical glasses, various optical systems and multi lens focussing objective in photo cameras.
