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 ...

Lenses are classified by the curvature of the two optical surfaces. A lens is biconvex (or double convex, or just convex) if both surfaces are convex.  If both surfaces have the same radius of curvature, the lens is equiconvex. A lens with two concave surfaces is biconcave (or ...

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.
