ABSTRACT
The optical design, as part of the optical engineering, is a process of selecting optical elements and putting them into a special order to the development of any simple or complex optical system that satisfies a customer's request. Optical design is the combination of art, science, a hard job and experience. To perform an appropriate design, a solid base is needed in geometric optics and physical optics, to understand in depth the theory of aberrations and especially the experience acquired over time through the trials and errors. Optical design software has the capacity to evaluate the attributes of an optical system, but as long as humans are making decisions, the designers will have to decide how the many trade-offs will be made. In the first-order system layout step, the designer aims to find the first approximation of the real optical system. The designer uses the lens design program to determine the optical parameters necessary to meet the required performance specification.
