Calcium Fluoride – CaF2 lenses, windows, mirrors, filters and prism . Calcium Fluoride (CaF2) can be used for optical windows, lenses, prisms and blanks in the Ultraviolet to Infrared region. Calcium Fluoride is a relatively hard material, being twice as hard as Barium Fluoride. Calcium Fluoride is grown by the Stockbarger technique.
The absolute luminescence efficiency (AE) of a calcium fluoride (CaF2:Eu) single crystal doped with europium was studied using X-ray energies met in general radiography.
Calcium Fluoride is used optically as windows, prisms and lenses transmitting from the vacuum ultraviolet (VUV) into the infrared. It is a physically and chemically stable optical material with good water and chemical resistance. Two qualities are manufactured, one for Visible and Infrared applications and the other specifically for Ultraviolet applications.
CaF2 windows have high damage threshold and can be used as mirror substrates for UV laser systems; Calcium fluoride windows have a wide transmission range and can be used in ultraviolet, visible and infrared applications. Due to its composition CaF 2 (Calcium Fluoride) has much longer useful life than most materials when used in a fluorine ...
Alibaba offers 234 calcium fluoride crystals products. About 46% of these are halide ( except chloride ), 1% are crystal crafts, and 1% are loose gemstone. A wide variety of calcium fluoride crystals options are available to you, such as electron grade, agriculture grade, and industrial grade.
Semiconductor Optics Calcium Fluoride CaF 2 Physical and Chemical Properties Calcium Fluoride (CaF 2) Physical & Chemical Properties Environmental Effects: Exposure to relative humidity at room temperature does not fog polished surfaces even after one month.
CRYSTALS CaF 2(Eu) Calcium Fluoride Scintillation Material CaF2(Eu) is a transparent material used for detecting γ-rays up to several hundred keV and for detecting charged particles. Because of its low atomic number, the material's photofraction is relatively small
Calcium Fluoride is a solid and when their are multiple molecules around they form a cube like structure that is centralized around the calcium molecules. The crystal lattice structure that Calcium Fluoride is also known as the fluorite structure. Figure# 1 shows what Calcium Fluoride looks like when its in the crystal lattice structure.
Apr 30, 2018· In calcium fluoride, each fluoride ion is surrounded by four calcium ions and each calcium ion is surrounded by eight fluoride ion. CaF2 form CCP type of arrangement. Thus, Ca2+ ions are present ...
2. The investigated material: Calcium fluoride The aim of this chapter is to make the reader familiar with the ionic crystal Calcium fluoride, and to emphasize some specific features of this material that are important in the context of this work. In the first part, the geometrical and electronic structure of the pure material is introduced.
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 Crystals Blanks Offer Highest Transmission Rates at 193 nm and Below The performance of microchips continues to double about every 18 months. The incredible progress that is being made in lithography and many other areas of technology owes a lot to calcium fluoride crystals. Low solubility and wide transmission make calcium flu-
In the early years of the 21st century, the stepper market for calcium fluoride collapsed, and many large manufacturing facilities have been closed. Canon and other manufacturers have used synthetically grown crystals of calcium fluoride components in lenses to aid apochromatic design, and to reduce light dispersion. This use has largely been ...
CaF2 Crystal Calcium Fluoride is used for optical windows, lenses and prisms in the 0.15 μm - 9 μm range. This material has found wide use in high power laser optics due to its low absorption. Polished surfaces are stable and will last several years under normal conditions.

Calcium fluoride is the inorganic compound of the elements calcium and fluorine with the formula CaF 2. It is a white insoluble solid. It occurs as the mineral fluorite (also called fluorspar), which is often deeply coloured owing to impurities.
♤Products > Optical Crystals >> CaF2 crystal CaF2, Calcium Fluoride Crystal. CaF2 window & lens - Calcium fluoride crystal provides great transmission from VUV to IR 0.13-11 µm). Sythetic CaF2 crystal is used to improve deep UV transmission and to increase the damage threshold.
Calcium fluoride is grown by vacuum Stockbarger technique. Material for IR use is grown using naturally mined fluorite, in large quantities at relatively low cost. Crystaltechno Ltd. grows calcium fluoride CaF2 crystals and produces CaF2 optics with diameter up to 380 mm, thickness 70 mm.
We supply Magnesium Fluoride Crystal, Calcium Fluoride Crystal and Barium Fluoride Crystal at very competitive prices.
Calcium fluoride is a mineral composed of CaF2. It occurs as cubic, isometric crystals and cleavable masses. When pure, it is colorless and transparent, or translucent with a glassy luster. Impurities cause color in the stone, and several varieties exhibit fluorescence.
