Abstract
Due to the development of 4K, 8K imaging technology, people have higher and higher requirements on the resolution and image quality of the picture. Demand for ultra-high definition video is increasing. However, there are still few lenses that can be used for 4k and 8k cameras, so the lens design requirements for ultra-high definition cameras for 4K and 8K shooting are increasing. This article focuses on the full-frame cameras. According to the existing ultra-high-definition lens, at first, the design requirements of the lens for the 4K camera are proposed, and then a high-resolution lens with a simple setup and a great imaging effect is designed. A lens system for ultra-high definition cameras was designed by using ZEMAX. The main optical parameters are: lens focal length is 50mm, aperture value F is 3.0, field of view angle is 46.8°, lens length is 69.29mm.The Sony IMX410CQK model image sensor is used.The design results show that the absolute value of the maximum distortion of the lens is less than 2%, the maximum field curvature is less than 0.2mm, and the MTF (modulation transfer function) of 40lp/mm within the 0.7 field of view is greater than 0.6, and the MTF at 80lp/mm is greater than 0.3. The lens consists of infrared filter, aspherical lens and ordinary lenses. The optical setup is compact and easy to process.
