Calcium fluoride crystal at 0.13 μ m~10 μ The light transmission performance is good in the wavelength range of M and the light transmission range is wide.
Calcium fluoride crystal has low stress birefringence and no obvious birefringence above 200 nm,
Calcium fluoride crystal also has the advantages of uniform and high refractive index, stable mechanical properties, no deliquescence, strong radiation damage resistance and so on.
Calcium fluoride crystal is an ideal material for making all kinds of optical windows, prisms and lenses.
It is used in infrared window, Fourier analysis, gas and liquid detection instrument, laser system, astronomical telescope, Mir / NIR imaging system, etc.
Deep ultraviolet (excimer level), ultraviolet level and infrared level of calcium fluoride materials and components could be provided.
Various orientation such as < 111 > < 110 > < 100 > can be provided;
Blanks of various shapes, such as round bar, square piece, kick-off blank, step blank, prism blank, angle blank, etc can be provided;
