Sapphire Windows Applications
Ebetter optics a wide range of opticla windows including round sapphire window, rectangle sapphire window, step sapphire window, and custom sapphire windows with various shapes and sizes.
Sapphire Windows Applications
Sapphire windows normally need to work under extreme operating conditions, so hard AR coating is required to withstand harsh environmental conditions and improve resistance to scratching.Sapphire windows are ideal for applications where high pressure, high temperature, high thermal loads, vacuum, scratch resistance, corrosion resistance, small coefficient of friction as well as optical and insulating properties are a consideration.
Sapphire substrate has a high refractive index, thus usually requires an antireflection coating on sapphire windows for sufficient transmission in the region of interest.
In some applications where sapphire windows needs to be soldered or bonded to metal. Synthetic Sapphire is a single crystal and high purity, so bare sapphire will not attach to braze or solder alloys on its own. Through solderable metallization on sapphire windows, hermetically sealed optics can be created for harsh or vacuum applications.
Ebetter optics is leading manufacturer of optical windows. We offers complete solutions for sapphire window fabrication including shaping, grinding, drilling, and polishing. We also provide coating and metallization solutions for sapphire windows to extend and optimize performance over a broad range of applications.
With more than 20s year diverse experience, Ebetter optics has developed effective methods to polish sapphire windows with low roughness, high surface quality and surface accuracy. Our typical achievable specifications for sapphire windows are: diameter up to 350 mm, length up to 500mm, thickness as thin as 200 microns, surface accuracy up to 1/10 lambda (lambda 633 nm), surface quality up to 10/5, and parallelism up to 5 arc seconds.
