High Temperature Resistant Plastic Lens Coating

Cameras installed in the automobiles contribute significantly to achieving safety in autonomous driving vehicles. In recent years, due to technological advances, automotive sensing cameras have become very important, because, to perform autonomous driving sensor functions, complex and precise controls are required. Also, since a high level of performance is required, the presence of high-quality lenses become extremely important.
Automotive lenses must have high durability over a long period of time. Plastic lenses being small and lightweight, have a high degree of freedom in design and good cost benefits. But plastic lenses have low resistance to temperature changes, so if the coating applied can not withstand the temperature changes, it results in formation of cracks and wrinkles on the lens surface. This flaw in the coating can damage the sensor and results in not being able to convey accurate information.
Therefore, Tamron have developed a coating technology for high-temperature resistant plastic lenses. By focusing on the formation mechanism of cracks and wrinkles, optimizing layer deposition conditions and applying coating, Tamron can make plastic lenses that can satisfy the demands of automotive lenses at a verification level.
