What is a sapphire window?
Sapphire Optical Windows
Sapphire has high compressive strength and is resistant to attack from strong acid. Ideal for high temperature, high pressure, or strong vacuum environments. Highly corrosion resistant. Transparent from 170 nm to 5.5 µm. Extremely hard and more durable than standard optical glass.
How are sapphire windows made?
Sapphire windows can withstand more than what quartz and conventional glass can, and at a fraction of the thickness. Sapphire crystals are “grown” in extremely hot ovens. The large, cylindrical boules are cut into sapphire rods, which are then sliced into thin discs, ground, and polished.Aug 1, 2017
What is sapphire lens?
Sapphire is an extremely durable and scratch resistant substrate which creates a rugged optical lens that can stand up to very harsh environments. Sapphire lenses will add to the long lasting value of your project or product. Perhaps you are constantly replacing your product's glass lenses due to damage.
What is sapphire glass used for?
The iPhone 5 and 5S made use of sapphire glass in their camera lenses, which made them virtually unscratchable. Plenty of high-end watches also use sapphire-glass faces for the same reason.Mar 6, 2015
Is sapphire birefringent?
Sapphire is also “birefringent” which is an optical refractive property that offsets wave transmission up to 0.8% at right angles to the optic axis. Birefringence is eliminated along the optic or C-axis of the crystal.
Is sapphire glass better than Gorilla Glass?
According to the earlier UBreakIFix video, Gorilla Glass can bend more during a four-point bend test than sapphire. Sapphire might be more scratch-resistant, but its ability to withstand a drop-induced bend or deformation isn't as great as Gorilla Glass.Sep 12, 2021
Does sapphire glass break easily?
While sapphire is almost entirely scratch-proof, it's still susceptible to cracks. "Sapphire is more brittle than glass," Raymond Soneira, president of DisplayMate Technologies told Business Insider.Sep 1, 2014
Is sapphire IR transparent?
Currently available infrared (IR) transparent materials typically exhibit a trade-off between optical performance and mechanical strength. For example, sapphire (crystalline alumina) is very strong, but lacks full transparency throughout the 3–5 micrometer mid-IR range.
Is sapphire glass expensive?
In general, sapphire crystal is the most expensive of all watch crystals. Highly regarded in the industry, sapphire crystals revolutionised watch crystals in general. This is actually not glass but a material made by crystallising pure aluminium oxide at very high temperatures.Aug 2, 2020

What is a sapphire window?
- Sapphire windows are highly tolerant of extreme temperature and pressure differences. These windows are commonly used as viewports enable viewing inside of vacuum chambers, or chambers containing high temperature plasma. Uncoated Sapphire is transparent across a wide wavelength range from 170 nm to 5.5 µm.

What is the orientation of the Saw series sapphire windows?
- The SAW series sapphire windows are provided with a random axis orientation. As sapphire is slightly birefringent, this may result in slight alteration of the polarization state of transmitted light. Sapphire windows are highly tolerant of extreme temperature and pressure differences.

Why Sapphire window is used in spectrophotometer?
- The sapphire window is perfectly corrosion-resistant and is widely used in such analytical instruments. In addition, sapphire window has a good transmittance from ultraviolet to infrared wide spectrum, which makes it more widely used in spectral range.

What is the difference between Sapphire and optical pressure windows?
- Sapphire pressure windows can be made much thinner than their optical glass counterparts due to sapphire’s high modulus of rupture. With a MOHS hardness of 9, sapphire is second only to diamond and it transmits from 190nm to 5000nm making it a great choice for UV applications and mid wave infrared.
