Sapphire Windows, featuring reliable mechanical/thermal/c
hemical robustness, large dielectric constants, and broad optical transmission from 150-5500nm, are excellent as both optical windows and protective windows in application contexts of more stringent requirements and extreme conditions.
The most distinctive feature of the sapphire is its unrivaled mechanical strength and ruggedness. The Mohs Hardness of Sapphire is 9, and it is the second hardest material that existed, ranking next to diamond. Sapphire windows are extraordinarily resistant to scratches and abrasions, in fact, sapphire windows can scarcely be damaged by other materials other than sapphire itself. This means sapphire windows could ensure clear optical apertures and maintain lucid sights even under attacks sand /grit and are exquisite for applications that will encounter splattering abrasive particles, such as drilling viewport windows, protective laser processing windows, and gun sights.
Due to the firm internal covalent bonding of sapphire, windows made from sapphire could be manufactured into much thinner pieces without fracture than the counterparts made from dielectric materials, and capable of withstanding high pressure. For instance, sapphire windows are often selected in avigation and deepwater contexts.
Furthermore, sapphire is high-temperature-tol
erable with a working temperature limit of up to 1600℃ and a melting point of 2000℃. Its high thermal conduction also endows sapphire windows with a unique advantage in handling high-temperature situations compared to other optical materials. Sapphire windows, therefore, are great options for high-temperature plasma chambers and combustion chambers, etc.
Sapphire windows contain solid chemical inertia to common acids/alkalines, with the sole exception being hot caustic salts. Sapphire outperforms other materials in coping with corrosive chemicals and erosive atmospheres, hence expanding the usage of sapphire windows into the domain of pharmaceuticals, medicines, and chemical facilities.
Besides, sapphire windows' broad spectral transmission encompasses 150nm-5500nm. Compared with the two common optical glass materials N-BK7 and UV Fused Silica, the transmission spectrum of N-BK7 is 350nm-2200nm, and UV Fused Silica 200-2200nm, sapphire excels N-BK7 with better UV functions and broader IR transmission and UV Fused Silica with less IR absorption. Sapphire windows could be utilized in critical optical operations of multi-spectrum.
Shalom EO offers various forms of Sapphire Windows made of Single Crystal Sapphire. Our single crystal sapphires are grown using the KY method, delivering materials of high purities without visible fractures, bubbles, and sub-grain. Large aperture sapphire windows with diameters up to 300mm are available, and surface qualities of 60/40, 40/20, 20/10, and Scratch/Dig are optional according to the precision requirements of your interest. We are also capable to provide high-precision ultra-thin sapphire windows with a large diameter-to-thicknes
s ratio.
Shalom EO’s blank sapphire substrates feature a broad transmission spectral range from UV to MIR and could cater to most optical applications without specific requirements. Single film MgF2 coatings and other AR coatings could also be furnished to increase transmission. Z-cut sapphire windows with the c-axis parallel to the optical axis to avoid birefringence in critical optical uses, and random-cut sapphire windows are both available. Besides, Shalom Eo also supplies metalized sapphire windows with nickel, chrome, and gold films on the window edges to enable direct soldering and brazing into your optomechanical assemblies.
Sapphire Window Kinds:
1. Optical Sapphire Windows:
Various shapes and forms of flat sapphire windows (circular, rectangular) and sapphire wedge windows, sapphire step windows are available in Shalom EO. The sapphire wedge windows comprise two unparallel planes and are utilized to deflect the incident beam to a specified direction at a certain deflection angle. Sapphire step windows are designed with stepped structures to ease the mounting onto certain mechanics (e.g. flanges).
2. Protective Sapphire Laser Windows:
Sapphire Protective Laser Windows are often utilized in laser processing as the front optic, protecting the laser lens from spattering substances during the processing course. Single crystal sapphire windows are suitable for the purpose due to their high-temperature endurance, outstanding mechanical hardness, and insusceptibility to high-power laser-induced damages.
Shalom EO provides sapphire laser windows with standardized specifications compatible with the laser machines from the world-leading laser producers. AR coatings with high thermal damage thresholds are procurable.
3. Other Special Sapphire Windows:
Sapphire windows could also be utilized as the sight glass and packages of machine interiors, insulating the machines from potential impairments resulting from high pressure, high temperature, chemical corrosion, etc. in applications such as underwater detection, high-pressure containers, oil deposit testing, and chemical operations.
Shalom EO offers High-pressure Protective Sapphire Windows, Deep Water Sapphire Windows, Corrosion-resistant Sapphire Tubes, and Sapphire Watch Glasses.
4. Metalized Sapphire Windows:
Metalized sapphire windows are furnished with metal films around the edges to enable hermetic soldering into metal housings. Metalized windows are often incorporated into endoscopes.
Shalom EO provides metalized sapphire windows of common endoscopic dimensions.
