It’s a familiar experience — it’s late at night and you’re driving along a dark, curvy road. You take a turn around a corner and all of a sudden an oncoming car practically blinds you with its high beam lights.
Thanks to the help of LEDs, that problem could soon be eradicated entirely. LEDs are quietly heading up a revolution in the automotive industry, leading to new vehicle designs and providing enhanced nighttime vision and safety for drivers.
There’s no mistaking the glow of an LED headlamp in the newer automotive models, especially in comparison to the yellow tinge of their older counterparts. LEDs are even serving as identifiers and differentiators between different makes and models.
For instance, there’s no mistaking the distinct shape of Audi headlights:
Or the four circles on BMW models:
Because they are smaller, run cooler and use less energy than traditional light bulbs and standard automotive headlamps, LEDs are catching on in the automotive industry — much like they are gaining popularity in commercial and residential uses.
But these LEDs aren’t just for looks and show.
For instance, when combined with cameras, these “smart” headlights are more than just a standard set of high beams and low beams. Instead, they can continuously alter light patterns to adjust to the immediate road and weather conditions. The system is so good at not shining light on vehicles traveling ahead of it that the high beam can remain on and adjust itself, even if eight cars are in front — giving nighttime drivers a better, safer experience.
If Americans are looking to reap the benefits of this sort of smart technology, they may have to wait a few years. Unfortunately, all cars sold in the United States must adhere to a specific light pattern, so all models are fitted with standard headlights.
Automakers are even projecting that a time will come when headlights will be able to project patterns like a foot path on the road to help pedestrians cross the street, or even lines to the left and right of the vehicle as it passes through a construction zone to avoid any hazards.
But until then, we can look in awe at the European cars and their “smart” headlights.

- Displays You Wear – Photonics Spectra: The augmented reality and wearable device industries are facing many challenges, specifically in the form of consumer devices. With the development of a wearable device, such as a watch, comes the need for a stronger screen that isn’t bulky or strange looking. Solutions to these issues are becoming easier due to innovations in protective covers, such as man made sapphire. Sapphire is more expensive than glass, but its greater scratch resistance, strength and durability allow products to be thinner, which can be a plus in wearables.
With the much anticipated release of the Apple Watch, the smart watch industry – and with it the sapphire industry – are back in the national spotlight.
Smart watches such as the Apple Watch are not only shaking up the wearables industry, but tipping us over the edge into a wearables revolution, predicted to be as transformative as smartphones and tablets. With each new release, sapphire continues to establish a clear role in the future of wearable technology.
So what has led sapphire to be the go-to screen choice for smart watches?
As the second hardest substance on Earth behind diamond, it is unsurprising so many smart watch manufacturers are going with sapphire for their high-end time pieces. Utilized by traditional luxury watchmakers for decades, a sapphire faceplate is hard, extremely rugged and scratch resistant – excellent qualities to have when a device is situated in a vulnerable position, such as your wrist.
In fact, in an effort to prove just how indestructible a sapphire display is, Apple fan site iPhonefixed recently made a video of a purported Apple Watch sapphire display enduring excessive abuse, including aggressive rubbing against a stone wall and a power drill. In the end, the Apple Watch display is shown 100 percent intact, surviving without a single scuff or scratch.
But Apple is not the first or only manufacturer to feature sapphire on its smart watches. At Mobile World Congress 2015, Huawei shook up the wearable world by announcing the Huawei Watch. Designed with a more classical look in mind than the Apple Watch, the smart watch’s stainless steel build and sapphire crystal face make it look and feel more like a traditional timepiece.

From semiconductor equipment components to camera lens covers, there are many intriguing uses for optical and non-wafer sapphire. Here’s a peek at five non-LED usages for Rubicon’s synthetic sapphire.
More than 40 different semiconductor equipment components are made of sapphire. Due to its ability to withstand very high temperatures, extreme environment processing and harsh chemicals like fluorine plasma and many acids, sapphire is ideal for equipment such as plasma tubes, heater plates, lift pins and chamber windows.
2. Medical Component
Sapphire products are used in a variety of medical applications, including dental braces, surgical blades, laser delivery windows, arthroscopy lenses and skull pins. When compared with traditional metal alternatives, medical sapphire components provide advantages of optical transmission, transparency for both aesthetic and performance improvements, high durability and precision, and also can be utilized for procedures requiring active imaging as sapphire does not impact imaging processes like metal.
3. Infrared (IR) Windows
Sapphire windows of optical quality are already being used for military sensing applications on aircrafts and missiles. In fact, sapphire IR windows are now beginning to be used on private, commercial and cargo aircraft to assist with landing in inclement weather.
4. Wafer Carriers
Sapphire is so durable that it is actually used to support other brittle wafers that are being processed, such as gallium arsenide and silicon carbide. These brittle wafers are mounted to sapphire so they do not break or get damaged during transit.
5. Durable Lenses and Windows
One of the largest optical applications for sapphire is in the form of lenses and windows. Due to its hardness and wide range of transmission from UV to Visible to IR wavelengths, sapphire lenses and windows are ideal for use in applications where there is a possibility of impact, scratching, high temperatures, chemical interaction or other harsh conditions. These lenses and windows are used in a wide variety of applications, such as camera lenses, military rifle scopes and as windows for sensors and laser transmission.
We are just scratching the surface when it comes to optical and non-wafer uses for sapphire. As research continues and new applications are discovered, you will see sapphire included in different types of products. Who knows, you may soon be seeing sapphire used for the armored windshields of military vehicles or even in hip replacements!

More than 7 million people in the United States alone are currently living with knee or hip replacements, 2.5 million of which have had total hip replacement (THR) surgeries, according to Mayo Clinic researchers.
While current metal-on-metal and ceramic endoprotheses have had a dramatic effect on mobilizing this fairly large segment of the population, these replacements must be replaced again after 15 to 30 years and have even been known to fail in just a few years.
Sapphire is breaking ground in the medical industry after having been successfully implanted into the hips of five patients.
Of this small experimental group, none have reportedly shown any complications since the implants were put in five years ago. Having long been considered an attractive material for artificial joint replacements, the success of these clinical trials proves sapphire has a promising future for use inside the human body.
One of the most important issues in the modern total hip arthroplasty (THA) is the bearing surface. Amongst other characteristics, extensive research has shown that durability and bio-inertness are necessary traits of materials used in hip replacements. The Ukrainian Academy of Medical Sciences, Kharkov, has been studying sapphire friction pairs, which prove to fit the bill.
Made from highly purified materials with crystals grown at 2,100℃ in a vacuum, sapphire friction pairs are aluminum oxides in the purest form have no porosity or grain boundaries. Under such conditions, additional purification of the material takes place and the content of the main substance (aluminum oxide) achieved is 99.99%.
These extremely pure sapphire friction pairs hold the following physical advantages over metal and ceramic endoprostheses:
- Biochemical inertness
- Low friction coefficient
- Extraordinarily high wear capacity
- Availability at a low cost
- Optical transparency
These characteristics make sapphire not only suitable for artificial bone replacements, but also other external medical applications, such as implants and braces. As clinical trials of the material continue, it is clear we are just scratching the surface of sapphire medical applications.
