Abstract
A specular reflection analyzer uses opposed parabolic mirror sections to direct a focussed beam at an angle of incidence against a sample surface and to receive a reflected beam at a corresponding angle of reflection. A first collimated beam of light is directed at a constant angle against the first parabolic mirror from a beam diverter movable parallel to the mirror's axis of symmetry and within the first collimated beam of light. Translation of the constant angle beam along a meridian on the surface of the first parabolic mirror changes the angle of incidence of a beam focused on the sample without changing the focal point. The light reflected from the sample is received in a corresponding manner by the second parabolic mirror and transformed into a collimated beam of constant angle to be received by a second beam diverter tracking the first beam diverter. Transfer optics may be used to adapt the apparatus for use in a conventional transmission spectrometer.
