  4. The etalon produces a fringe pattern in He–Ne laser light and could be stabilized indefinitely, if necessary, to within ~1 MHz by locking to a He–Ne fringe. The FSR of 6328-Å He–Ne laser corresponds to 8 MHz at 12 μm.

Fig. 1

PQ5 (15) doublet in ν9 of ethane near 809 cm−1 as calibrated with the 50-cm confocal etalon. The etalon pattern and ethane spectral were recorded simultaneously. The etalon fringes give a direct measure of the effective instrument function during the scan.

Fig. 2
Fig. 2

Spectra of a single fringe of the 50-cm confocal etalon. Single sweeps are 0.01 sec in duration. The etalon fringe width is 2 MHz; the 64-sweep average (0.7-sec integration time) fringe profile of ~7-Mhz width is due to broadening by laser frequency jitter. Laser frequency modulation due to refrigerator shocking is apparent in the fourth single sweep.
