What are Functional Crystals?
A wide range of functional crystal materials is used in various optical applications. While optical glass is commonly used as a transparent material, different functional crystal materials, primarily monocrystalline materials, are required for diverse applications due to their unique functionalities:
In contrast to glass, birefringent crystals can exhibit birefringence, which is a requirement for various types of polarizers, wave plates, birefringent tuners, and other optical components. Commonly used birefringent crystal materials include YVO4, �±-BBO, quartz, calcite and sapphire.
The lattice symmetry of a crystal material is not too high (such as a triangular, quadrilateral, or single prism), and it can exhibit nonlinearity. Nonlinear crystals are primarily used for nonlinear frequency conversion but also find applications in optical modulators like the Pokel cell.
A wide variety of functional crystal materials can be used as laser crystals, serving as host materials for laser-active dopants (rare earth ions or transition metal ions). They typically exhibit relatively high transition cross sections, small gain bandwidth, and good heat conduction compared to laser-active glasses. In general, they also allow for higher doping concentrations.
In some cases, functional crystal materials are used in spectral regions where glass does not have a wide enough wavelength range and high transmittance. In particular, various materials such as zinc sulfide (ZnS), zinc selenide (ZnSe) and Sapphire (Al2O3) are used as infrared crystals, and other materials such as lithium fluoride (LiF), calcium fluoride (CaF2) and magnesium fluoride (MgF2) are used as ultraviolet crystals.
Some functional crystal materials, such as terbium gallium garnet (TGG), exhibit the Faraday effect (polarization rotation caused by magnetic fields), and they can be utilized in devices like Faraday rotators and Faraday isolators.

Introduction: When it is done in a proper way, a piece of glass can adjust the light transmission rate passing through it by changing its transparency or colour. This process is called chromogenic. There are several chromogenics. They are electrochromic, photochromic, thermochromic and gasochromic etc. The most popular is electrochromic. There are two types of electrochromic, PDLC (polymer dispersed liquid crystal) and SPD (suspension particle device). And PDLC is most frequently used. PDLC glass is a light control glass. It can regulate and adjust the light intensity or light transmission passing through the glass. Sometimes, it is known as intelligent glass, magic glass, privacy glass, smart glass or switchable glass. Polymer dispersed liquid crystal film is a light changing liquid crystal film. It is base on the especial performance of liquid crystal material ¡ï¿½plight valve¡ï¿½+. Crystal tiny drop in this film under external electric field rank, distribute in order, when incident light completely permeate, film display clear and colorless state; when external electric field disappear, crystal tiny drop in this film rank order is disturbed, which is made incident light scattering to create ¡ï¿½psandblasted glass¡ï¿½+ effect. Also let positive and negative type of PDLC crystal dye bond make full color light valve film, through change voltage size and frequency to show kinds of color. Regulating light crystal film firstly applies in NASA manned spacecraft glass new material project and obtain success. This material through decade developing after invented, more and more applies in civil product market, because of productive procedure perfecting step-by-step and cost continuously reducing. Regulating light glass is one of the intelligence type of top grade function glass, it adjusts sunlight change from beat and dispersion through voltage on and off, it made glass transparence and protective intimity double requirement come true, even if it is not transparence, light transmitting is also good, ray is enough in room, that is all curtain can not come true, furthermore, it acts as insulation and reflection to infrared, to make inside of room warm in winter and cool in summer, moreover it is environmental protection and energy saving products. This products adopt laminated glass process, are made of regulating light film compound in two piece of glass, it makes use of liquid crystal optic anisotropy to come true regulating light film photo-electricity performance.
