Abstract

A multipass vernier tandem Fabry-Perot interferometer is easily constructed and aligned when the two scanning mirrors are mounted on a common scaning stage. Using such a system we obtain an ultimate resolution of 10** minus **3cm** minus **1 and a maximum scanning range, free of overlapping orders, of greater than 50 cm** minus **1. Using a 5 plus 4 pass arrangement a contrast VM GT TH 10**1**7 is obtained which, together with a high overall luminosity, permits simultaneous resolution of both weak spectral features near zero energy shift and low-frequency Raman bands. In addition to constructional details of this system a discussion is presented of the alignment procedure for uniform transmission in tandem operation, and it is demonstrated how the alignment requirements ultimately limit the performance of any tandem system to an ″effective finesse″ of less than 1000.
