Emerging optics, such as those in mobile phone cameras, AR/VR goggles and LiDAR devices, reach the limits of traditional PVD technologies and demand optical coatings with conformality only achievable by ALD.
Coating complex optics made easy. Current optical coating methods are well-established for low cost, tolerable process temperature and high throughput. However, traditional PVD coating technologies lack high conformality, making emerging microstructured, curved and freeform optics difficult to coat. For coating complex optics, atomic layer deposition provides advantages over PVD, like precise thickness control and uniformity, without sacrificing film performance.
