  • Sapphire
    Sapphire is a gemstone variety of the mineral corundum, an aluminium oxide (α-Al2O3).
  • Potassium bromide
    Potassium bromide (KBr) is a salt, widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries, with over-the-counter use extending to 1975 in the US.
  • Poly(methyl methacrylate)
    Poly(methyl methacrylate) (PMMA), also known as acrylic or acrylic glass as well as by the trade names Plexiglas, Acrylite, Lucite, and Perspex among several others (see below), is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass.
  • Calcite
    Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).
  • Zinc selenide
    Zinc selenide (ZnSe) is a light-yellow, solid compound comprising zinc (Zn) and selenium (Se).
  • Zinc sulfide
    Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS.
  • Lithium fluoride
    Lithium fluoride is an inorganic compound with the chemical formula LiF.
  • Magnesium fluoride
    Magnesium fluoride is an inorganic compound with the formula MgF2.
  • Arsenic triselenide
    Arsenic triselenide (As2Se3) is an inorganic chemical compound, a selenide of arsenic.
  • Calcium fluoride
    Calcium fluoride is the inorganic compound with the formula CaF2.
  • Barium fluoride
    Barium fluoride (BaF2) is a chemical compound of barium and fluorine and is a salt.

    Tellurium dioxide (TeO2) is a solid oxide of tellurium.
  • Magnesium oxide
    Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide).
  • Yogo sapphire
    Yogo sapphires are a variety of corundum found only in Yogo Gulch, part of the Little Belt Mountains in Judith Basin County, Montana, United States, on land once inhabited by the Piegan Blackfeet people.
  • Picarin
    Picarin is a plastic used to make optics such as lenses for terahertz radiation (THz radiation).
  • Transparency and translucency
    In the field of optics, transparency (also called pellucidity or diaphaneity) is the physical property of allowing light to pass through the material without being scattered.
  • Yttrium aluminium garnet
    Yttrium aluminium garnet (YAG, Y3Al5O12) is a synthetic crystalline material of the garnet group.
