The Development Of Flare With Multiple Anti-reflection Coating

At present, the need of high quantity image that the digital photography equipment has acquired makes the camera lens design is more complicated than before, and it is easy to produce scattering light between the internal lens surfaces and the lens berrel. When shooting in the light, the scattering light even will cover the original actual image, and the manifestations of flare are diverse, they will affect the quantity of the image we finally get.We use the multiplayer thin film to realize antireflection of the single optical lens in visible broadband and at wide-angle incident, and it will greatly reduce the reflection light and the scattering light of the whole lens. Because of the reduce of the unneeded light reach the film, we can reduce flare effectively and increase and advance the quality of the image.In this article, we have studed the coating design of the multilayer thin film and the craft of the coating produce, and realize the anti-flare design of the special lens.
