Abstract

An interferometer spectrometer aligning apparatus and method are disclosed, in which the laser beam generator, which is in the instrument to provide data controlling clock signals, is also used to accomplish initial (and as needed) alignment of the instrument. The laser beam is directed through a target both on its way from the laser generator to the interferometer, and as it is reflected back from the interferometer, thereby validating the perpendicularity of the reflector to the axis of the interferometer. A semi-transparent mirror, i.e., a small beamsplitter, is used in the path of the laser beam ahead of the interferometer beamsplitter, thereby enabling portions of the laser beam to go into both the interferometer and the sample chamber. A second semi-transparent small mirror (beamsplitter) is also used in the path of the laser beam, for the purpose of providing two parallel laser beams both in the interferometer and in the sample chamber, the parallel beams being used for a plurality of optical checking and adjusting tasks.
