Analysis of quasi-parabolic reflectors with a microwave lamp installed at the input of a prismatic light guide

A technique for calculating a quasi-parabolic reflector containing a spherical electrodeless lamp in a translucent microwave resonator placed at the input of a prismatic light guide is considered. The light-intensity curves calculated with the ROTREF computer code are analyzed. These curves are calculated for admissible values of the reflector’s turning angle, different diameters of the prismatic light guide, and different shifts of the lamp along the reflector axis. The three most typical positions of the lamp inside the quasi-parabolic reflector are found and features of these positions are discussed.
