Glass surface INDEX

Other Applications. The refractive index of siUcate or borosiUcate glass can be modified by the addition of cesium oxide, introduced as cesium nitrate or carbonate. Glass surfaces can be made resistant to corrosion or breakage by surface ion exchange with cesium compound melts or solutions. This process can also be used for the production of optical wave guides (61).

Refractive birefringence is determined by the refractive index profiles for the TE and TM polarization of the waveguide structure and is a function of the depth x counted from the glass surface ... 

To make a nonreflective coating [antireflection (AR) coating] on a glass surface in air the value of Hf must lie between that of air and the glass. The reflectivity will be a minimum for a A/4 film. Putting R equal to zero yields a value of the refractive index of a film that will give no reflection at all ... 

A ray of light passing through water (refractive index, n = 1.33) in a glass tank (refractive index 1.58) hits the water/glass surface at an angle of 23°.
