The curved CMOS bends its edge area for a better edge illuminance which effectively corrects the field curvature and image aberration as well as simplifies the optical system. In this paper, a full frame 24-megapixel camera lens of f=50mm and F#/1.8 with 5 pieces of ordinary glasses is designed by Zemax, introducing the curved CMOS and three aspherical surfaces into the design. The system uses a full frame (36mm*24mm) curved surface sensor with a viewing angle of 46°, an effective focal length of 50mm, and a total length of 82.5mm. The full viewing field MTF is greater than 0.4, the maximum distortion is less than 3% and the relative illumination is greater than 0.75. All of these optical results enable not only an excellent imaging quality but a simplified system with the introduction of the curved sensor.

As far as resolution is concerned, a system with pixels exceeding 4K (3980*2040) or 8K (7680*4320) is called Ultra HD. In this paper, to fill the gap in UHD testing and evaluation, we take a full frame 8K HDR camera equipped with a zoom lens as an example, evaluating the system performance by a comprehensive test. Next, according to the results, a new testing process including three indicators with corresponding criteria is designed to make a supplement to BT.2020 criterion and offers an integrated test for 8K camera lenses.
