Could someone tell me how to go about measuring the complex index of
refraction of glass in the mid-infrared region (1000 to 2000 cm-1). I am
doing some interesting spectroscopy in this region and one of our
substrates is Corning 7059 glass slides and from our previous experiments
it is clear that this glass has optical constants that differ from values
listed in the literature. Any information regarding either a source of
complex index of refration measurements or an accurate method to measure
such values would be greatly appreciated.

Try using an ellipsometer; they are available at most universities.
The most powerful version of an ellipsometer is a variable angle
spectroscopic ellipsometer or V.A.S.E. made by the Woollam company in
Lincoln, NE. Measuring your glass n and k would be a piece of cake.
