Fine Fluorides
Calcium Fluoride :
CaF2
Powder for Optical Materials
MPIL high purity CaF2 powder is suitable for optics applications.
CaF2 is transparent over a very broad range of wavelengths – from deep UV to IR. For this reason it is used for manufacture of optics components such as lenses, prisms and windows. Other favourable properties include very low solubility in water, low refractive index and dispersion, high laser damage threshold, high chemical resistance to most acids (other than sulphuric acid) and a wide working temperature range from cryogenic to 500°C.
Some important end uses of CaF2 are:
- Excimer laser optics for microlithography
- Optics for high resolution cameras, telescopes, microscopes and spectroscopes
- UV and IR optics
- Thermal imaging, Night vision systems
- Photoluminescence
