    Abstract: A radiation guiding structure for incoherent radiation is disclosed in which a collimated beam is transmitted through a light pipe having high radition throughput. Radiation losses due to absorbance are minimized by: (1) matching the area of the beam and the light pipe passage; (2) minimizing the number of reflectances of a given ray by reducing the angular divergence of radiation in the beam; and (3) using a reflective coating on the wall of the light pipe which has the low point of its reflectance curve at a relatively high grazing angle.

    Abstract: A probe is disclosed for use in internal reflection spectroscopy at locations immersed in containers. Two parallel light pipes, located inside the probe, are used to carry radiation toward and away from an internal reflectance element (IRE) located at or near the bottom of the probe. The IRE, which is exposed to analyte in the container, has a radiation-entering surface and a radiation-exiting surface which permit collimated radiation to fill both light pipes. No beamsplitter is required to separate pre-sample and post-sample radiation. In one embodiment the IRE is a rod having concave conical entering and exiting surfaces, and a separate radiation-direction-reversing element is mounted on the tip of the probe. In another embodiment the IRE is itself a direction-reversing means mounted on the tip of the probe.

    Abstract: A spectroscopy system is disclosed which obtains analytical information from an internal reflectance element (IRE) deeply immersed in a container. The system is designed to provide adequate radiation throughput under difficult conditions. A plurality of embodiments deal with the optical element(s) at the bottom of the tube and the optical element(s) above the tube which direct post-interference radiation downward in the tube and receive post IRE upward radiation for re-direction to the detector.

    Abstract: A spectrometer system is disclosed in which a single ended internal reflectance element (IRE) is readily insertable into, and removable from, liquid samples being analyzed. The IRE is carried by an articulated housing construction having enclosed radiation passages, through which radiation is directed by a plurality of mirrors. The IRE-supporting enclosure is pivotally mounted by means of aligned rotatable members, which permit the IRE to be moved into and out of samples without disconnecting or re-purging the enclosed radiation passages.

    Abstract: The present invention provides a radiation source which essentially matches the throughput radiation of the source to the throughput radiation of the interferometer; and it provides the maximum throughput usable by the interferometer with a minimum use of power at the source. The infrared source in this invention combines a radiating element having the optimum area with a hollow, inwardly-reflecting sphere, whose center is at the radiating element and whose exterior has a single aperture which causes radiation to fill the entrance field of view of the spectrometer.

    Abstract: Spectrometer sampling chamber structures are disclosed which avoid purge loss during loading and unloading of samples. In two disclosed versions, a plunger carries the sample, and fits closely inside a fixed tube, into which it is inserted for sample illumination. Sample loading and unloading is accomplished without fully removing the plunger from the tube. Also, an automatic purging flow of gas from the interior of the spectrometer is caused during insertion of a new sample. In a third disclosed version, vertically stacked sample holders move through a vertical chute into which they are inserted to the top of the sample chamber, and from which they are removed at the bottom of the sample chamber.
