Ever since the iPhone 5 S. apple has claimed to have sapphire crystal as their iPhone camera lens, this includes the iPhone 6 the success and even. The iPhone Essie sapphire crystal is a human-made material that is extremely hard and almost impossible to scratch with everyday objects since it ranks about a nine on most Kayla pardon is right next to diamonds.
Hence, it’s a pretty big selling point when a company brags about using it, T.
A cell is another company that brags about sapphire crystal on their watches; it is even written right here on the back, so let’s compare Tissot sapphire hardness with apple’s sapphire hardness these pics let me know.
Where an object falls on most California’s glass even tempered glass or gorilla glass will always follow a 5 or 6 plastic will be a 2 or 3 and sapphire will be an 8 or 9 as you can see from my picks on this watch face there is no market Intel on those eight pick leaves.
The first visible groove, if you remember from my iPhone 7 durability test a few days ago when I scratch the camera lens on the iPhone 7 with my picks, left a visible mark on Adamo 6, which led me to assume that. The lens is regular tempered glass says it has the same hardness level. It was only after I made the durability article that I noticed apple still bragging about the sapphire on their iPhone 7, so I figured. It was time to test all of the sapphire iPhone lenses now full disclosure. This hurts me even more so than snapping a phone in half.
I’m a camera guy, so deliberately scratching a camera lens even for science is extremely painful. I retested the iPhone 7 and got the same result as six a seven and an eight pack all leave their mark scratching much. Sooner than sapphire crystal should scratch the sapphire lens on the iPhone Essie also scratched with the 6 and 7 the iPhone 5 S. showed marks the 6 and 7. Even the iPhone 6 scratched at a 6 and 7, so we can easily conclude that each of the iPhone sapphire lenses is much softer than the Tissot watch face.
At this point, I thought the case was closed, and I got ready to post a video saying apple just isn’t using the sapphire crystal. Still, I grabbed a diamond tester that I had lying around, tested the outer glass surface, and was willing enough. It tested positive for a sapphire. This is strange because, as we’ve seen, the hardness level does not match what sapphire should be when I check the underside of the lens; the sapphire reading is much lower also interesting.
I’ll explain that in just a second, as you can see when I test my Tissot watch face, it is off the charts and sapphire readings, but that is only. Because it is a larger surface area and more comfortable for the machine to identify just for reference, this is a real sapphire. It’s a pretty small stone. However, still a level 9 on the most scale of hardness, this is just showing the mineral picks in action and control for the tester tool, so both companies claim to have sapphire, so why is there a difference in hardness.
I looked at both my Tissot watch and iPhone camera lens under a microscope. I found some interesting things, first of all, remember that this scratch on the watch happened at a level 8. We can see the damage pretty clearly under the microscope, the thin groove, and the little chippings that permanently disfigure the crystal.
But if we check the sapphire iPhone 5 S. camera lens under the microscope, we can see something entirely different remember that this is the most 6 line. This is the most 7 line. This crack here happened as I was lifting lands out of the iPhone frame. Level 6 and 7 picks did permanent damage. However, under the microscope, they look like small fractures instead of scratches still very permanent and even permanently disfiguring a lens, so it’s pretty clear.
We’re working with two different qualities of crystal here now that we’ve seen this damage let’s figure out why apple’s Lynn starts to fracture Adamo 6 when it should be resilient to at least an eight like. On the Tissot watch or level 9, as we saw on the actual sapphire stone, so I checked apple’s patent for their sapphire information and found a few strange things. I will link this form down the video description if you’re interested in looking at it yourself 1 of the very first things.
It says is that apple’s patent is related to the thin sapphire lemon. It’s been down here talks about laminating regular glass with the sapphire coating instead of having the whole thing the sapphire interestingly enough because the glass may provide cost savings over sapphire. It also references camera lenses explicitly, so is that why the lens is fracturing maybe it’s not solid sapphire, it could be just a thin laminate on top of regular glass because it would be more cost-effective. I realize that to analyze the Linz before posting an article.
I need some bigger toys I headed over to the university. They have an XRF machine X. ray fluorescence as a non-destructive analytical technique used to determine the composition of materials. That this particular machine is only qualitative, not quantitative so, it won’t tell us the percentage of each element just if the item existed in the specimen when I tested the outside of the lens. I get a massive reading of aluminum oxide, which means that the lens is most definitely sapphire on the exterior when I check the inside lanes.
I get no reading for aluminum oxide, but I do get a reading for silicon, which is an ingredient of glass. This means that the underside of the lens is made of or coated with glass but the. XRF machine does not tell how thick each side is, so to find the thickness of each layer of the Lins, I need an even bigger toy now this machine as an electron microscope costing close to $1000000. I wish I had one in my basement. Still, Santa keeps on ignoring my letters either way and this test.
I have broken the actual iPhone 7 wins out of the phone, and here we are looking at the cross-section of the broken Linz this year is the total insignis. This electron microscope is showing the actual elemental makeup of the lands downs up for science. The wind was clean before analyzing, and this is what we see during the scan the different colors represent. The various elements are found in Linz. The carbon and silicon are not ingredients of sapphire, only the aluminum oxide, so from this image, we can safely assume that the sapphire.
We’re looking at is not here; there are pretty hefty contaminants like the carbon and silicon. Remember how my diamond detector tool had a lower reading on the inside of the lens because there is a silicon layer that you can see here. Still, it is incredibly small compared to the rest of the glass, so it’s pretty much a nonissue. I bet that the inner layer is more to minimize reflection or something minor because of structurally.
It doesn’t seem like it would add any value. The vast portion of the lens is aluminum oxide. The graph here is quantitative, so it gives us a certain percentage of elements of aluminum oxide carbon and silicon in this particular reading. Let’s look at another segment. Remember that this site is the exterior that decides is the interior of the phone.
This is the profile of the crack; it has an incredibly thin coating of something on the inside Linn’s niobium. Silicon niobium improved the refractive index of optical glass, allowing for smaller and lighter lenses so, and it looks like that particular element is intentional. The majority of the lens body is aluminum oxide, which is what we call Safire. However, we still have quite a bit of carbon, and that’s the main impurity here is the quantitative graph again the coal is still a decent-sized chunk the niobium and silicon or just on that. Very tiny inner layer now, let’s take a look at the elemental analysis of the sapphire crystal on my T.
So watch the only two elements found on the surface of the watching the scan our aluminum and oxide no carbon impurity also the ratios. Of the Tissot, sapphire is very different than the apple sapphire apple only has a 2 or 3 percent difference between the aluminum and oxide, and Tissot has an almost 10 percent difference. No, I am not a chemist, a geologist, or an engineer.
I graduated in business, but these numbers sure are impressive between a lens that does fracture. Ellen’s that doesn’t after filming and editing this video, I noticed one of M. K. B. H. D.’s most popular videos, which I will link in the video description. It is about the prototype sapphire screen. Of the iPhone 6 that he posted a couple of years ago, he came to the independent conclusion that it’s crashed at a seven on the most scale, which if that prototype was indeed a real piece of apple sapphire.
It does match the same recipe that they are currently using for their camera lens; it makes me wonder if the sapphire screen prototype and the current sapphire camera. Lens bull scratch early is the sapphire apple watch made of the same week recipe and the bigger question of how impure can your sapphire B. and still call.
In conclusion, it sapphire because my results show that the lens scratches earlier than sapphire don’t mean it’s a bad Linz; it is still scratch-resistant. Just like glasses and the pictures are always great, it’s just not a scratch-resistant as we all thought it would be if you like seeing technology reviewed from the inside.
