A novel means of provided velocity control of an interferometer wherein one of the moving components includes the beamsplitter element is introduced herein. Using a moving beamsplitter and coupled flexure mounting allows improved velocity control because the low mass of the beamsplitter enables the systems disclosed herein to respond faster than conventional mirror velocity controlled interferometer instruments with a resultant lower velocity error so as to provide a more stable and lower noise spectra from the analytical instrument. The control of the velocity of the beamsplitter and if desired, one or both of the configured mirrors, reduces the time wasted changing velocity at the ends of each scan. The result is an increase in data collection available in any given experiment time frame. Such desirable arrangements of the present invention thus allow scans to be collected at higher rates, which beneficially increase the ability to monitor rapidly changing systems. |
