This interferometer consists of a beam splitter and two mirrors placed in nearly orthogonal planes (one being static, the other oscillating). The beam splitter is used to separate the incident beam into two identical rays, to send them be reflected on each mirror and to recombine the rays in order to obtain an interference image, which depends on the difference of the optical path induced by the mirror oscillation. The obtained interference image or «interferogram» corresponds to an energy variation as a function of each wavelength time, with maximum when waves are in phase, and minimum when waves are in phase opposition. Other ranges available upon request Zero drift: ± 1% full scale / 30 days Span drift: ± 1% full scale / 30 days Repeatability: ± 2% full scale Lower detectable limit: 2% full scale Response time: < 120s depending on the gas Interferometer resolution: 8 cm-1 Measurement cell: multi-reflexion, 5 m Power supply: 220 V, ± 15%, 50-60 Hz, 200 VA Dim.: rack 19“, 616 x 483 x 220 mm (DxWxH) Weight: 20 kg approx Operating temperature: + 10°C to + 35°C Therefore, the interferogram corresponds to an energy variation as a function of time, and the optical spectrum corresponding to an energy variation as a function of frequency is obtained by Fourier Transform signal processing.
