Sapphire window

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 situation
 

Uncoated sapphire has excellent surface hardness, and the transmission range extends from the ultraviolet to the mid-infrared wavelength region. Sapphire can only be scratched by a few substances other than it, and is not soluble in water, common acids or alkalis at temperatures up to about 1000 ° C. Sapphire has high temperature resistance, good thermal conductivity, high hardness, infrared transmission, and good chemical stability. Widely used in many fields of industry, defense and scientific research (such as high temperature resistant infrared window, etc.). Our sapphire window is a z-axis section, so the c-axis of the crystal is parallel to the optical axis, eliminating the birefringence effect of transmitted light. Sapphire can be divided into two types: coated and uncoated. The uncoated design is used for applications in the range of 150 nm-4.5 μm, while the anti-reflection coating is coated on both sides with antireflection coatings, designed for 1.65 µm-3.0 µm (- D) or 2.0 µm-5.0 µm (-E1).
