ABSTRACT:
A spectrometer is disclosed having an interferometer in which: (a) the variable-length arm has a moving retroreflector (copy A to A in summary). The pivoted linkage comprises three or more arms each having its upper end pivotally connected to a supporting structure and its lower end pivotally connected to a carrier for the retroreflector. The stationary folding mirror blocks approximately half of the open face of the retroreflector, causing the radiation which enters the unblocked half of the retroreflector to be reflected back to the retroreflector after it has traveled diagonally across the retroreflector and then been reflected toward the folding mirror.
