Abstract
The resolving power of spectrometers depends upon the inverse of the difference of path created by the analytical device. For most of the apparatus to create a great difference of path means to restrict the angular aperture of the beams. Consequently, the throughput decreases as the resolution increases and the resolution is frequently noise limited in the infrared part of the spectrum. A set of confocal interferometers makes possible to increase both the throughput and the resolving power (P. CONNES). This device is easy to use, at least for very high resolving power. Some results of analysis with a resolving power of $10^{6}$ will be presented.
