Reflectometers
First Claim
1. An optical reflectometer, comprising:
- means, including at least a front wall, for defining a chamber;
means defining an incident light path extending from said front wall of said chamber-defining-means to said chamber;
carrier means, removably disposed within said chamber and having means for accommodating said incident light path defined within said chamber-defining-means, for removably guiding a test object relative to said carrier means and for carrying said test object, along a fixed path intercepting said incident light path, to a fixed position located within said incident light path; and
photoresponsive means for receiving light reflected from said test object.

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.

13. An optical reflectometer, comprising:
-
means for defining a chamber and including a front wall and a pair of opposed sidewalls extending rearwardly from said front wall; first means defining an incident light path extending from said front wall of said chamber-defining-means to said chamber; carrier means, removably disposed within said chamber behind said front wall and between said opposed sidewalls and having means for accommodating said incident light path defined within said chamber-defining means, and having slot means defined therein for removably guiding a test object relative to said carrier means and for carrying said test object, along a fixed path intercepting said incident light path, to a fixed position located within said incident light path; second means defining a reflected light path extending from said chamber to said front wall of said chamber-defining-means; and photoresponsive means disposed outside of said chamber for receiving reflected light from said test object along said reflected light path.
