Source yeux1122 broke the news on his Naver blog, saying that he learned from Apple’s supply chain that the company is actively testing a new anti-reflective optical coating technology. This technology promises to significantly improve photo quality by significantly reducing photography artifacts such as lens flare and ghosting.
Supply chain sources revealed that Apple is considering introducing advanced atomic layer deposition (ALD) equipment into the manufacturing process of iPhone camera lenses. ALD is a thin-film deposition technology based on the continuous use of a gas-phase chemical process, which is a method of depositing substances on the surface of a substrate layer by layer in the form of a single-atom film. ALD is a true nanotechnology that enables the deposition of ultra-thin films at the nanometer scale in a precisely controlled manner.
Specific to camera lenses, the ALD process is mainly used to spray anti-reflective coatings. When strong light sources such as the sun directly illuminate the lens, distortions such as stripes and halos may appear in the final image. ALD technology can effectively reduce these artifacts and improve image quality. At the same time, ALD applied materials can also prevent environmental damage to the camera lens system, ensuring that the sensor can capture light efficiently.
The blog post further states that Apple plans to apply this process to the iPhone Pro models, which may appear on the upcoming iPhone 16 Pro series or next year’s iPhone 17 Pro series.
