This paper studies to design of the two beams interferometer and analyzes single lens performance. The reference beam and the test beam were established by multi-configuration mode of ZEMAX optical software to analyze interference fringe of concave lens, concave lens and optical plate. In general, the manufacturing process of the lens is the measurement of the lens after making it. Although there is only one design example for the concave lens, concave lens and optical plate respectively, the technique can still be applied to the general concave lens and concave lens. We have firstly created to do in the reverse way, that is, after the simulation of the lens's measurement, and then make it. So, it can lower the cost of the product and also decrease the time of research and development. This technique will provide practical experience in evaluating optical product performance quickly before mass production and good yield rate for the optical engineers.
