Usage of Focal Length Analyzer

The focal length is an important parameter to evaluate an imaging system. But for real thick lenses, or systems consisting of several lenses and mirrors, the effective focal length is not easy to calculate. By using the Focal Length Analyzer, the effective and back focal length of an Optical Interface Sequence (OIS), a Single Optical Interface or a Spherical Lens can be obtained. The Focal Length Analyzer can also be applied in a Parametric Optimization. The corresponding result can be configured as a merit function for optimization.
