Transmitted light

Description

The light that passes through a material. Transmitted light is produced by placing a light source on one side of a material and a detector, such as a camera or human eye, on the opposite side. Visually, the light that passes through the material can be used to detect flaws, fractures, density variations, and color. Transmitted light is measured in terms of transmittance, which is the ratio of the transmitted light to the incident light expressed either as a fraction or as a percentage.
