Pittcon ‘93 marked the 10th anniversary of the introduction of a microscope attachment designed specifically for Fourier transform infrared microspectroscopy. The first commercial microscope developed for FT-IR spectroscopy was designed by Spectra-Tech, Inc., under the direction of then-owner D. W. Sting, in fulfillment of a contract with C. T. Foskett of the Digilab Division of BioRad. Digilab recognized a growing interest in the market for an FT-IR microscope and contracted with Spectra-Tech to design and build a microscope accessory for Digilab's FT-IR spectrometers. This microscope was introduced at the 1983 Pittsburgh Conference.

Linking microscopy with Fourier transform spectroscopy was a very significant event, but the foundation of infrared microspectroscopy can be traced back to 1949. The explosive growth in the use of infrared-absorption spectroscopy following World War II led researchers R. Gore (in the U.S.A.), and R. Barer, A. R. Cole, and H. W. Thompson (in England), to investigate (in 1949) the possibility of recording infrared spectra of microscopic samples.
