Customized CZ Transparent Sapphire Optical Window For Optical Equipment

Customized Flat Sapphire Watch Glass With Transparent Color

The window is a flat plate with two parallel or wedge-shaped surfaces, and is usually used as a protective window for electronic sensors or external environment detectors. The window does not change the magnification of the system. Substrate materials include various sapphire, optical glass, K9, ultraviolet fused silica, infrared fused silica, and calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), silicon (Si) And other crystal materials, and provide various optical coatings such as anti-reflection coatings, high-reflection coatings, spectroscopic coatings, and metal coatings. Broadband antireflection coatings can be used in the ultraviolet, visible, near-infrared and mid-infrared bands.

The sapphire window is a flat polished product based on single crystal sapphire processing. The sapphire protective window is a special window that uses the pressure, abrasion, and high temperature characteristics of sapphire to protect the observer, the inside of the instrument and the inside of the container.

Single crystal sapphire windows are very suitable for demanding applications (such as laser systems) because of their extremely high surface hardness, high thermal conductivity, high dielectric constant, and resistance to chemical acids and alkalis. Since the hardness of sapphire is second only to diamond, and its structural strength is very high, the thickness of the sapphire window made by enhanced light transmittance is thinner than that of the general high-dielectric window. In terms of chemistry, sapphire is a single crystal of aluminum oxide (Al2O3), which is very suitable for transmission between 0.2 and 5.5 μm. In general optical applications, the basic needs of customers can be met without coating. Our products can also be coated, silk-screened or special heat treated according to customer needs to meet the special needs of customers.
