Fabricating high-power electronics and light-emitting diodes can be difficult because of the need for a transparent window material.
UniversityWafer, Inc.'s optical sapphire wafers is the best option for producing high-power electronics and light-emitting diodes because they have many advantages over other materials. Sapphire is highly transparent, easy to process into complex devices, and resistant to damage from heat and radiation.

Sapphire windows is one of the hardest materials after diamond. They are often used in extreme enviorments including space with radiation is an issue. For medical research/production sapphire is used in microfluidic devices. Optical sapphire is a benefit for military hardware as it performs as its very wide optical transmission that is better than traditional glass. Sapphire's wide optical transmission band from UV to near-IR, (0.15-5.5µm) No Ultra-Violett radiation darkening protects hardware.
An optically transparent sapphire wafer can be used to produce high-power electronics and light-emitting diodes. The materials used in the process are silicon carbide, quartz, glass, and lithium niobate. The following are the main advantages of sapphire as a transparent window material. The first advantage is that sapphire is a highly transparent material and can be processed into various complex devices.
Infrared spectroscopy can detect defects in optically transparent materials such as sapphire. Because sapphire is an excellent infrared window, multiple-detector IR cameras can be used for the process. The measurements obtained in IR are similar to observations made at visible wavelengths. The researchers used a multi-detector IR camera to measure radiation intensity on a rake face of a sapphire wafer. The device uses a focal-plane array of 256x256 Indium-Antimonide detectors.
The main benefit of an optically transparent sapphire wafer is its ability to transmit light in a narrow wavelength range. The wavelength range of the material is 150-6000 nm. It is strong enough to be useful even at close wavelengths. Its transparency makes it a great infrared window. In addition, it makes a very useful optical substrate. The advantages of an optically transparent sapphire wader are many.
Optically transparent sapphire wafers are very difficult to inspect using conventional equipment. A sapphire tool is difficult to use because the temperature at the interface increases from the minimum near the cutting edge to the maximum near the edge of the contact. Moreover, a sapphire tool does not leave any deposits near the cutting edge. Unlike diamond tools, the tools do not leave any traces of deposits on the rake face.
Sapphire wafers are used in teh optoelectronics and microelectronic industries. Unlike less expensive Silicon, Sapphire wafers are used as insulator. Sapphire's Advantages over other substrates include:
UniversityWafer, Inc have all diameters/dimensions from 1mm round to 200mm and thicknesses as thin as 100 micron sapphire available.
