Abstract

In the past decade advances in microprocessors have been applied in FT-IR spectrometers to deliver higher data system performance at substantially reduced cost. Now, advances in microprocessors and signal processing technology are being applied to overcome current performance limits in the FT-IR optical bench, and considerably expand their functionality. This paper describes the design and performance of a new generation of research-grade interferometer, the 896, using state-of-the-art technology. The major enhancements are: rapid auto-align (allowing interchanging of beamsplitters); dynamic alignment (giving active stabilization and allowing high performance operation over a wide variety of scan conditions); enhanced stability rapid-scan mode with general purpose kinetic software; step-scan mode (0.004 Hz to 800 Hz) with variable phase modulation; and dynamic range extension.
