| Abstract: | According to application requirements,one optical system with 90° line of vision for 1/4″CCD stomatology endoscope was designed.The system has 62° field of view and one F/7 aperture.The modulation transfer founctions in all fields are excellent on 80 lp/mm with a long depth of field.The illumination on image plane is uniform,and the maximum lens dimension is less than 4.6 mm. |
