In recent years, using the capsule endoscope to inspect the pathological change of digestive system and intestine had a great break-through on the medical engineering. However, there are some problems needs to overcome. One is that, the field of view was not wide enough, and the other is that the image quality was not enough well. The drawbacks made medical professionals to examine digestive diseases unclearly and ambiguously. In order to solve these problems, the paper designed a novel miniature lenses which has a wide angle of field of view and a good quality of imaging. The lenses employed in the capsule endoscope consisted of a piece of plastic aspherical lens and a piece of glass lens and compacted in the 9.8mm (W) *9.8mm (L) *10.7mm (H) size. Taking the white LED light source and the10 μm pixel size of 256*256 CMOS sensor under considerations, the field of view of the lenses could be achieved to 86 degrees, and the MTF to 37% at 501p/mm of space frequency. The experimental data proves that the design is consistent with the finished prototype.
