The sapphire optical wedge window has similar function with traditional optical window. It also has two well-polished planes, and the two planes form a angle. Sapphire wedge can be used as isolating components. In addition to features similar to normal wedge windows, the sapphire wedge window has a harder, stronger, and more wear-resistant properties. It is widely used in some special environments.
Wedge window is an optical element with plane-inclined surfaces, usually the faces are inclined toward one another at a very small angles. It diverts light toward its thicker portion. Wedge prisms can be used as isolating components. Wedges may also be used to produce a small deviation which doesn't allow return to source.
