Refractive Index, Dispersion, and Birefringence of Silicon

The refractive index of each of the four common silicon carbide polytypes has been measured over the visible range. The data were analyzed in an attempt to relate the birefringence to the relative hexagonal character of the polytype. A general relationship exists, namely, that the birefringence increases with increasing hexagonal character of the polytype.

How should You Choose Lenses when Matching Glasses?

The reinforcing film is a layer of metal oxides and coupling agents with the similar refractive index to the lens. It has many characteristics, such as high hardness, high adhesion, high light transmission, etc., which can effectively improve the wear resistance of the lens.

Abdellatif Bachar - Process Engineer - STMicroelectronics

The consequence of these observations is that a control of refractive index in the range of [1.9–2.5] at λ = 633 nm and optical bandgap in the range [2 eV–3.8 eV] have been obtained which induces that these coatings can be used as antireflective coatings in silicon photovoltaic cells.

Silicon carbide - Wikipedia

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions

List of refractive indices - Wikipedia

Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion.Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature, pressure/stress, etc., as well on precise material compositions

Optical Materials: Double-Sided Lapping and Polishing

In theory, the process requires a minimum of three parts. The actual nuer is determined by part quantity, part size, and machine size. With double-sided lapping and polishing (DSLP), the optical components are held in geared or sprocketed carriers that are driven in a planetary motion covering the full surface of the lapping plates and are subject to continually changing direction of rotation.
