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.

BaF2 window crystals or Barium Fluoride window crystals, with their extremely broad transmission range from the deep UV to LWIR spectrum, are prevalent for Infrared applications requiring additional transmission in the Ultraviolet region. BaF2 window crystals are excellent when being used for IR spectroscopes and as viewport windows for thermal imaging inspection in electric power facilities and petroleum industries. A low refractive index of 1.48 implies BaF2 windows have high transmission rates without anti-reflection coating.
BaF2 window crystals has similar properties to CaF2, the difference mainly lies in that barium fluoride window is more resistant to highly energetic radiation, and with an equivalent thickness, the transmission range of BaF2 window extends approximately 1 micron further into the long-wave IR region than calcium fluoride. BaF2 window crystals could also accommodate high-temperature environments up to 800 â??. However, exposure to moisture will increase its sensitivity to temperature and reduce its transmission rate to UV lights. If you would like to know more about BaF2 IR windows, BaF2 window crystals prices, please do not hesitate to contact Ost Photonics.
