Paper Abstract

A 64 X 64 Mercury-Cadmium-Telluride (MCT) focal-plane array detector attached to a Fourier transform infrared (FT-IR) microscope has been used to spectroscopically image a cross section of a laminated polymer film in the fingerprint region of the infrared spectrum (1800 - 900 cm-1). Image contrast is achieved due to the intrinsic chemical nature of the sample at each pixel location in the image. This technique is clearly able to identify the individual layers in this polymer film laminate. Infrared spectra of individual pixels in a 7.5- micrometer-thick adhesive tie layer of this polymer laminate show no interference from adjacent layers.
