Product Details
Barium fluoride (BaF2) crystal belongs to Cubic crystal system, with good moisture resistance, melting point of 1280 ℃, high use temperature, little change in refractive index in a wide wavelength range, and a wide light transmission range. Between 0.2 and 10 μ Within the wavelength range of m, the highest transmittance can reach over 90%. BaF2 crystal has excellent optical and mechanical properties. This makes BaF2 crystal widely used in infrared and ultraviolet windows as well as prism substrates.
In addition, BaF2 crystal also has excellent scintillation performance (because the crystal has fast and slow luminescence components, can simultaneously measure energy spectrum and time spectrum, and has high energy resolution and time resolution, BaF2 has broad application prospects in the field of high-energy physics, nuclear physics and Nuclear medicine.
application
BaF2 crystal is widely used in infrared and ultraviolet windows as well as prism substrates.
It has broad application prospects in high-energy physics, nuclear physics, Nuclear medicine and other fields.
characteristic
BaF2 crystal has excellent optical and mechanical properties. The refractive index does not vary significantly over a wider wavelength range and a wider transmittance range. Between 0.2 and 10 μ Within the wavelength range of m, the highest transmittance can reach over 90%.
BaF2 crystal also exhibits excellent scintillation performance (due to its fast and slow emission components, it can simultaneously measure energy and time spectra, and has relatively high energy and time resolution).
