Abstract

Disclosed is a system for enabling easy sequential setting of different Angles-of-Incidence of a beam of electromagnetic radiation to a surface of a sample system involving regression based methodology for evaluating and compensating the effects of the presence electromagnetic beam intercepting angle-of-incidence changing systems, including where desired, parameterization of calibration parameters.
