What are Sapphire Windows?
Sapphire windows are made from sapphire crystals and are very resilient. Unlike ordinary glass or similar optical materials, sapphire optical can handle high-stress environments without experience any major deformations. If you want windows in an environment with high pressure, high temperature, bigger thermal loads, and other such harsh environmental factors, sapphire windows are the best solution for you.
Benefits of Sapphire Optical Window
Sapphire optical windows provide a wide range of benefits that make them a worthwhile investment. Here’s a look at some of the biggest advantages for you to consider:
Handles High or Low Temperatures – Sapphire optical windows can handle up to 2000°C without softening. The material has a melting temperature of around 2030°C, which makes it a good choice for places like furnace windows or space exploration. The material can also handle lower temperatures and is used in submersible
Can Handle Pressure – A sapphire optical window can handle a lot of pressure without sustaining much damage. It is a hard material that will withstand high winds and sustained pressure whenever necessary, which is one of the reasons why the material is used in industrial applications so often.
Has A Good Transmittance Range – This material has an excellent transmittance range. It can be transparent to any kind of light between 0.3 μm (UV) and 5 μm (IR), which makes it ideal for barcode and IR scanning equipment as well. The material is also resistant to darkening caused by UV rays so you don’t need to worry about replacing it any time soon.
Resistant to Abrasions – Sapphire optical windows are resistant to scratches and abrasions as well, the material has a hardness of 9 on the Mohs hardness scale. It will take a lot to cause scratches or blemishes on this window’s surface.
Suitable for Extreme Environments – The combination of the points mentioned above makes the window suitable for harsh environments. If you’re looking for a transparent material that can handle extreme environments, sapphire is the right choice.
Good Thermal Conductivity – The material also has good thermal conductivity so it offers some protection when used as a window for a furnace or other such environments.
High Mechanical Strength – Sapphire optical windows also have much higher levels of mechanical strength compared to other optical materials. It can handle more stress from physical forces like impact or sustained pressure than any other optical material, which is one of the reasons why it is used in military applications so often.
Chemically Inert – A sapphire optical window is chemically inert and non-reactive. It can handle acids and alkali without sustaining any damage. If you want something resistant to harsh chemicals, this product will be ideal for you.
Sapphire windows are resilient, reliable, and effective, which makes them a good investment. We offer affordable and high-quality windows made from carefully sourced materials. You won’t need to worry about the window’s overall performance or durability.
Applications of Sapphire Optical Windows
As mentioned before, a sapphire optical window has several applications. The strong and resistant material can be used in industrial environments, laboratories, medical facilities, and more. Here’s a look at some of its more popular applications:
Furnace Viewing Ports – A strong sapphire window can form a good protective barrier between you and the furnace without compromising your ability to see what's going on the side.
Barcode Readers – Sapphire glass’s transparency makes it easier for people to scan barcodes accurately. The surface is resistant to scratches so there’s nothing to disrupt the scanner’s ability to read the code.
Submersible ROVs – Submersible ROVs need to withstand different levels of pressure and different temperatures, which is why they can benefit from a sapphire optical window. The material can handle pressure and the shifting underwater environment without degrading over time.
IR Analytical Devices – Submersible ROVs need to withstand different levels of pressure and different temperatures, which is why they can benefit from a sapphire optical window. The material can handle pressure and the shifting underwater environment without degrading over time.
Gas Analytical Devices – Sapphire is chemically inert and stable. Exposure to gas and other chemicals doesn’t cause any degradation, which is why it is often used in these applications.
Oil Analytical Devices – The inert nature of the sapphire optical window makes it a good choice for oil analytical devices.
Military Optical Requirements – Military optical devices need more resilient materials. Drones, vehicles, measuring devices, and even camps can benefit from something like a sapphire optical window.
Space Exploration Optical Requirements – Space is a very hostile environment and weaker materials can degrade in it easily. That’s one of the reasons why sapphire optics are used often in space exploration devices or vehicles.
Medical and Research Applications – Sapphire glass is often used in medical and research environments because it is bio-inert. It doesn’t react to biological materials and chemicals, which makes sapphire glass a good choice for laboratories and research equipment.
As you can see, sapphire optical window products have a wide range of applications. We provide several combinations of this product so you can choose what works for you. Clients can choose between 2.5mm and 200mm diameters, squares and rectangles ranging from 1.0mm to 200mm, thickness ranging from 0.2mm to 150mm, and much more.
