Optical design of apochromatic objective with wave disparity method

Optical design of apochromatic objective used wave disparity method in this paper. Based on the relationships between spherical aberration and wave disparity, color aberration and wave front chromatic aberration, the equations of structure parameter and wave disparity are deduced. By use of the equations to get the original structure, which take advantage of the computer dealing with the complex questions, and make the questions easily to be solved. Apochromatic objective design of long focus collimator is one of the two key problems of optical design. According to the program of optical design, we use the glasses that made in china to design some high quality apochromatic objectives of long focus collimator. In the same way, we can design the apochromatic photograph objective by different glasses. In this paper, we give some examples in order to validate the method of optical design. The result indicates that the method is simple, and the optical design of apochromatic objective is high quality, and the cost is cheap.
