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.
