SYNTHESIS OF OPTICAL SYSTEMS: STRUCTURAL DEVELOPMENT AND DESIGN

摘要

In the previous two parts of this report the concept of an 'Effective Thin Lens' (ETL) and of an 'Equivalent Gaussian Lens' (EGL) was developed. Along with this con- cept a generalized definition of 'Shape Factor' or 'Load Distribution Factor' had been proposed and used to implement a simple yet effective method of 'ab initio' development of multi element lens system to meet specific working requirements. The present report concerns itself with indicating the possibility of effecting linear optimization of paraxial and first-order design. The possibility stems from the fact that the ray configurations in the object and the image spaces of the two element system being changed shall remain unaltered when the 'LDF' and/or the separation are changed to modify the aberra- tions.
