Barium fluoride optical window plate

Optical window plate is a kind of double-sided polished parallel plate, the surface quality of optical glass with optical level, will not change the multiplier of the optical system, Commonly used as protective glass for optical detectors, sensors, optical lenses, detectors, etc. Substrate materials include various optical glass, ultraviolet fused quartz, infrared fused quartz, calcium fluoride(CaF2), magnesium fluoride(MgF2), zinc selenide (ZnSe), germanium(Ge), silicon(Si) and other crystal materials. And provide anti-reflection coating, high reflective coating, spectroscopic coating, metal coating and other optical coating. When choosing an optical window, consider whether the material transmission and mechanical properties of the window fit your application. Yukang photonics can provide a variety of materials to respond to a variety of industrial production scenarios.

The optical window filters produced by yukang photonics are divided into three categories: ultraviolet window, visible window and infrared window. The best solution can be selected according to the specific requirements of customers.

While serving as window protection, it does not lose light ehergy, improve transmittance, increase hardness, reduce reflection and increase surface smoothness. Application fields involve various aspects, such as: smart home system, biometrics system, intelligent robot accessories, laser barcode scanning, infrared remote control, medical device display window, camera UV mirror, etc.

Product features

Barium fluoride is similar in nature to calcium fluoride, but it is more resistant to high-energy radiation, is not resistant to water, and its performance significantly deteriorates when it comes into contact with water at 500°C, but it can be used in dry environments at 800 °C. Barium fluoride is usually used in applications of 8-14 nm for thermal imaging Windows, rapid scintillator materials, thermal imaging Windows, high energy physics experiments, etc. Barium fluoride has a wide transmittance range and good transmittance in the wavelength range of 0.13μm ~ 14μm, making it an ideal material for making various optical Windows, prisms, lenses and other optical elements. Barium fluoride window plate is widely used in infrared window, gas analysis window, oil and gas detection, high power laser, optical instruments.
