Abstract:
1. An optical analysis system utilizing transmission spectroscopy for analyzing specimens of at least one of liquids and solids, comprising: a source of optical energy; a specimen; a movable optical energy transmission window; a fixed optical energy transmission window, whereby the fixed transmission window remains fixed relative to the source of optical energy, the specimen selectively being positioned between the movable and fixed optical energy transmission windows and directly contacting both the movable and fixed optical energy transmission windows for analyzing the specimen, the optical energy being transmitted through one of the windows, the specimen, and the other window to obtain encoded optical energy as a result of transmitting the optical energy through the specimen; and a detection system for receiving the encoded optical energy for analysis, the movable optical energy transmission window being selectively movable relative to the fixed optical energy transmission window to repeatedly and precisely produce an optical path length between the movable and fixed windows and to repeatedly and precisely align and make readily accessible both windows and the specimen.
