Abstract

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 five 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.
