Abstract
A 1.5mm focal length, F/4and F/3.75, miniature fisheye all spherical optical lens systems with 220 degree full field of view are designed in this paper, a brief discussion for a series of limiting factors is achieved, the performance evaluation is done by ZEMAX optical design and analysis software, which shows that the two designed fisheye lenses are perfect lateral color and axial chromatic aberration corrected, the maximum wavefront OPD at the full FOV is 0.6λ and 1.2λ, the RMS spot size is 3.75-3.9microns across the full FOV in both lens systems, and have diffraction encircled energy, as above 80% energy can be included in 4.8 μm radius circle. Finally, the modulation transfer function of these two designs produces a high-resolution projection with uniform in brightness over the entire range of field angles for security, monitoring, and tracking applications.
