Hanzhong Brisun Optics Co., Ltd. Is the high High precision optical element manufacturer provides customized production of Various optical lenses, including spherical lens, cylindrical lens, optical window, mirror, prism, filter, metal base mirror and other high-precision optical elements. The base materials include various optical glass, fused quartz, calcium fluoride (CaF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), sapphire, metal and other materials. And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.
Barium fluoride (BaF2) window
Ø between 200nm - 12 μ Excellent transmittance between M
Ø resistant to high-energy radiation
Ø non coated version can provide high transmittance
Barium fluoride is a fast scintillator that can be used to detect X-rays, gamma rays or other high-energy particles, such as 511 keV gamma photons in positron emission computed tomography (PET). BaF2 can also be used to detect high-energy neutrons or to separate them from simultaneous gamma photons by using pulse shape discrimination technology.
Due to Barium fluoride (BaF2) window chip has wide bandwidth transmittance and can transmit from far ultraviolet to long wave infrared. Therefore, this product can be used in various applications, such as infrared spectroscope. The low refractive index of barium fluoride is 1.48, which can provide high transmittance without antireflection film. In a dry environment, barium fluoride window sheets can withstand ambient temperatures up to 800 °, but prolonged contact with water will reduce the transmittance in the vacuum ultraviolet range. However, compared with calcium fluoride window sheet, barium fluoride window sheet has lower resistance to water. BaF2 window sheet is the most resistant optical fluoride to high-energy radiation, but has lower UV transmission. BaF2 has a Knoop hardness of 82.
In addition, we have thousands of kinds of stock, such as quartz plano convex lens, quartz plano concave lens, quartz biconvex lens, quartz biconvex lens, cylindrical lens, prism, filters, windows, beamsplitter and so on. The price is preferential and the quality is excellent, which can meet your demand for a small order.
