Calcium fluoride crystal is an optical material. CaF2 crystal has excellent ultraviolet transmittance, high laser-damage threshold, low axial and radial-strass birefringence, and etc.
Calcium fluoride is an ionic crystal with the fluorine anions in a simple cubic array and calcium cations in half of the cubic sites of the structure. The calcium ions can also be thought of as being on an "expanded" fcc lattice with the fluorine ions causing their lattice separation to be 0.39 nm. This representation is shown in the lower diagram.
Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF 2. It is a white insoluble solid. It is a white insoluble solid. It occurs as the mineral fluorite (also called fluorspar), which is often deeply coloured owing to impurities.
Wafers. Services. Calcium Fluoride (CaF2) Calcium Fluoride is a cubic single crystal which has a good transmittance from 170nm to 8000nm. The crystal is resistance to water, and organic chemicals and many acids, including HF. But it will slowly dissolve in nitric acid and it is sensitive to thermal shock.
Calcium fluoride (CaF2 or fluorite) is grown by vacuum Stockbarger technique in diameters of up to about 250mm.. Crystal for infrared use is often grown using naturally mined fluorite to reduce costs. It will not have the best transmission in the UV and VUV and can have absorption bands at …
Calcium Fluoride Crystal Substrates Description. Calcium fluoride crystal substrate is made of calcium fluoride, which is the inorganic compound of the elements calcium and fluorine.It is a white insoluble solid. It occurs as the mineral fluorite (also called …
Calcium Fluoride (CaF2) Single Crystal Our standard sizes range from 5.0mm to 190mm diameter however, larger sizes are available upon request. We offer CaF2 blanks and components in a variety of crystal orientations, <111>, <100>, random or other orientations upon request. Magnesium Fluoride (MgF2) Crystal
CaF2 and various combinations of fluoride compounds can be made into synthetic crystals with applications in lasers and special optics for UV and infrared. In commercial applications, Cannon uses CaF2 in some of their high-end optical lenses, as shown in Figure 3.

Calcium fluoride. Occurring in nature as the mineral fluorite or fluorspar. It is the primary source of fluorine and its compounds. Pure calcium fluoride is used as a catalyst in dehydration and dehydrogenation and is used to fluoridate drinking water. (From Merck Index, 11th ed) Medical Subject Headings (MeSH) Calcium difluoride is a calcium salt.
Calcium fluoride(CaF 2) is a very important optical functional crystal, which has good optical properties, mechanical properties and chemical stability.It can be used as optical crystal, laser crystal and inorganic scintillation crystal. It has a wide transmittance range (0.125-10 μm), and is widely used as optical medium from vacuum ultraviolet to mid infrared.
Calcium fluoride crystal optic rectangle, 41mm x 23mm x 6mm, polished both sides Calcium fluoride sputtering target, 12.7mm (0.5in) dia x 2.5mm (0.098in) thick Calcium fluoride, puriss., meets analytical specification of DAB, 99.0-102.0%
The CaF2 crystals may thus serve as pH-controlled reservoirs of fluoride ions on the enamel or in plaque and release fluoride during caries challenges. It is suggested that calcium fluoride is an essential phase explaining important aspects of the mechanism of topically applied fluoride, contrary to what was assumed in the past.
In dry environments, calcium fluoride can be used up to 1000°C, but it does not begin to soften at 800°C. Calcium fluoride is inert to organic chemicals and many acids, including HF. It will slowly dissolve in nitric acid. Fabrication: Calcium fluoride can be machined with standard diamond tools and water-based coolants. The material
