Refraction is the change in direction of light when it passes from one medium to another. The working of a lens is based on the refraction of light when they pass through it. Lens is a piece of ...

This lens type is unique as it curves outward from one side and inward from the other side. These lenses are used for balancing purposes where other lenses cause spherical aberrations. The laser beam ...

Labeled negative lens diverging the light rays passing through the lens from an axis and convex lens converges the light rays passing through the lens to a point. The convex or biconvex lens is ...

Understanding what a lens is first requires understanding what light is. Light is electromagnetic radiation that exhibits properties of both waves and particles. It is currently understood to be ...

Abstract: This paper reports a novel method for the fabrication of 3-dimensional (3D) Polydimethylsiloxane (PDMS) micropillars with concave and convex lens tips in a one-step molding process, using a ...

A spherical mirror is that mirror whose reflecting surface is the part of a hollow sphere of glass. Spherical mirrors are of two types: concave mirrors and convex mirrors. In a concave mirror ...

In a ray diagram, a concave lens is drawn as a vertical line with inward facing arrows to indicate the shape of the lens.
