ABSTRACT:
An accessory for use with spectrophotometers for conducting IR emission spectra analyses of samples comprising a heated highly-reflecting surface for receiving the sample, an apertured reflecting mask located over the sample, and a curved reflector for collecting emissions from the sample via the aperture over a large solid angle to increase the signal-to-noise ratio.
