ABSTRACT:
An optical reflectometer includes an optical head having a measuring chamber defined therein and a measuring zone defined within the chamber. A pair of non-parallel bores are defined within the front wall of the head and optically lead into the measuring chamber so as to intersect at the measuring zone. A light source is optically associated with one of the bores while a photodetector is optically associated with the other one of the bores. A carrier, having a cut-away section defined within its front wall for accommodating the light path defined by the light source, the measuring zone, and the photodetector, is removably disposed within the optical head and serves to carry, and position, a test object with respect to the measuring zone, the object, in turn, being removably disposed within the carrier.
