Optics and Optical Coatings

Zinc-selenium is the most commonly used optical material that enables the transmission of infrared light.

Silicon is a monocrystal mainly used in semiconductors and does not absorb in the IR range from 1.2 µm to 6 µm.

Germanium as a monocrystal, which is mainly used in semiconductors, is non-absorbing in IR ranges from 2 µm to 20 µm.

Corner cubes have the property that light incident on the prism face is deflected 180 degrees regardless of its angle of incidence.

The internal reflection type parabolic lens is an optical element that can collect light on the emitting end surface when incident light from different directions is reflected from the streamlined side surface.

Dove prisms have the useful property of completely inverting an image by 180 degrees.

BK7 equilateral prisms are commonly used for splitting light into its different colors.

SiO2 equilateral prisms are commonly used for splitting light into its different colors.

S-TIH11 equilateral prisms are usually used for scattering the light into its different colors.

The knife-edge prism is polished on the sharp edges of the rectangular faces and has no chamfers on these edges.

The knife-edge prism is polished on the sharp edges of the rectangular faces and has no chamfers on these edges.

BK7 Light Pipe is an optical element for illuminating a uniform brightness distribution from a light with a non-uniform brightness distribution.
