Getting The Best Results From Fourier Spectrometers (FTIR)

Dr. Fred Goldstein in his 16 February 2004 Film Star News had the following comment:

"...it appears that the current consensus on ‘FTIR vs. Grating IR' is that FTIR instruments are unsuitable for optical measurements.  If you disagree, or have evidence to the contrary, we'd like to hear."

Having been associated with FTIR since 1957, I felt compelled to respond to that comment.  In general, I have to agree that the application of FTIR can lead to results that are prone to photometric errors.  However, there are things that can be done to overcome the limitations of FTIR for optical measurements.
