| 摘 要： | 由于大视场会带来大的垂轴像差，尤其是畸变，以及结构的不对称性， Ｃ Ｃ Ｄ 针孔物镜一般视场不超过７０°。应用非球面光学设计，不仅使视场大于等于８０°，且畸变较小。此外，通过实例对球面设计与非球面设计进行比较，论证了非球面光学设计的优越性。

| Abstract: | As the distortion of the broad field optical system is very serious and the composition is not symmetrical, the field of the CCD pinhole objectives is usually no more than 70. In this paper, by the aspherical optical design, this kind of lens has not only the more than 80 field but also the small distortion. It is also proved that the aspherical optical design is superiors to the spherical optical design. |
