The oxide is used to make special high refractive index glass for camera lenses.
2.
Only the base is silvered, and the prism is made of high-index glass.
3.
The Protar's front achromat used older glass, but the rear achromat used high index glass.
4.
These high-index glasses ( inaccurately known as " crystal " when used in glass vessels ) cause more chromatic dispersion of light, and are prized for their diamond-like optical properties.
5.
This utilises a property of and other materials; specifically that a thin layer of gold on a high refractive index glass surface can absorb laser light, producing electron waves ( surface plasmons ) on the gold surface.
6.
The prism coupler consists of a near cube of high refractive-index glass and a second thin film at the bottom that contacts the waveguide film and serves the function of partially containing the guided wave over the coupling distance.
