Dichroic Glass (7.58 ct)

Lab-Made Dichroic Glass. Optical Glass “X-Cubes” consist of a Cross Dichroic Prism comprised of 4 triangular prisms fused into a cube. The dichroic film can consist of over 100 layers which ultimately combine Red, Green and Blue coloured beams to form a prismatic, rainbow-coloured reflection.
A Dichroic cube is a special arrangement of filters and prisms that can reflect different colours of light in different directions. When light enters one face of the cube, the special reflection coatings inside the prism either reflect light or pass through light depending on its wavelength. These coatings are called dichroic coatings, or “two-coloured”, referring to the two colours that split off when they meet the coating. One coating reflects only red light and sends it out one side of the cube, and another only reflects blue light, sending it out another side. The remaining light passes straight through the cube.
