Abstract
A condensing and collecting optical system includes a collimating reflector and focusing reflector. The collimating reflector includes a portion of a paraboloid of revolution having a focal point and an optical axis. The focusing reflector includes a paraboloid of revolution having a focal point and an optical axis. A source of the electromagnetic radiation placed at the focal point of the collimating reflector produces a collimated beam of radiation. The focusing reflector is positioned so as to receive the collimated beam and focus it toward a target positioned at the focal point of the focusing reflector. To achieve maximum illumination at the target, the collimating reflector and the focusing reflector are so constructed and positioned so as to achieve preferably about unit magnification between the source and its focused image, although other magnifications may be achieved.
