convex lens
->
converging lens
Also known as convergent lens or convex lens. A lens that converges an incident bundle of rays to a focus.
concavo-convex lens
A lens with one concave surface and one convex surface; synonymous with meniscus.
converging lens
Also known as convergent lens or convex lens. A lens that converges an incident bundle of rays to a focus.
center of curvature
The center of the sphere of which the surface of a lens or mirror forms a portion. Each curved surface of a lens has a center of curvature; the surfaces may be convex or concave.
collective lens
A convex or positive lens that serves to collect energy and direct it into subsequent system optics.
concave
Concave is an adjective used to describe a surface or shape that curves inward or has a hollow or recessed appearance. In the context of geometry or optics, a concave shape is one that curves or...
convergence
1. In optics, the bending of light rays toward each other, as by a convex or positive lens. 2. Turning in the eyes to view a near object. 3. In a television picture tube, the crossing of the...
converging meniscus
A converging lens with one convex and one concave surface.
convex
Convex is an adjective used to describe a surface or shape that curves outward, bulges, or has a rounded and outwardly extending appearance. In the context of geometry or optics, a convex shape is...
convexo-concave lens
->
meniscus lens
A meniscus lens is an optical lens that has one side that is concave (curved inward) and the other side that is convex (curved outward). It can be categorized into two types based on its optical...
curvilinear distortion
A lens aberration in which the focal length varies radially outward from the center of the field. It has the effect of making a straight tangential line in the object appear curved in the image,...
cylindrical lens
A cylindrical lens is an optical component that has different curvatures along its two orthogonal axes, resulting in a shape resembling a cylinder. Unlike spherical lenses, which have the same...
