Optical coating. An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflective coating, which ...
One-way glass (4) used in a teleprompter. A one-way mirror is typically used as an apparently normal mirror in a brightly lit room, with a much darker room on the other side. People on the brightly lit side see their own reflection—it looks like a normal mirror. People on the dark side see through it—it looks like a transparent window. The ...
The glass reflects a room hidden from the viewer (left), sometimes called a blue room, that is built as a mirror-image of the scene. If the mirror-image room (left) is darkened, it does not reflect well in the glass. The empty room (top) is brightly lit, making it very visible to the viewer.
Silvering. Silvering on the inside of a glass test tube. Silvering is the chemical process of coating a non-conductive substrate such as glass with a reflective substance, to produce a mirror. While the metal is often silver, the term is used for the application of any reflective metal.
Front projection—the background is projected onto a two-way mirror, which reflects the image onto a highly reflective surface. A front projection effect is an in-camera visual effects process in film production for combining foreground performance with pre-filmed background footage. In contrast to rear projection, which projects footage onto ...
A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...
Objects are often placed inside the box. The first objects placed inside the environment were two white boxes. Another common version first used to test photon mapping includes two spheres: one with a perfect mirror surface and one made of glass. The physical properties of the box are designed to show diffuse interreflection. For example, some ...
