The capsule endoscope currently on the market only images the front field of view. Furthermore, the folds and loops of intestinal tissue in the human body cause a large number of blind spots in the rear field of view. In this paper, we report the design of a capsule objective lens that simultaneously images the front (0°-80°) and the side rear (50°-80°) fields of view. The objective lens is 15.6 mm in length, and the maximum radial diameter is 8 mm. An OH02A10 imaging chip ensures a high-resolution image (maximum cut-off frequency >0.5 at 89 lp/mm) and provides good image quality.
