Abstract
A simple device for the two dimensional IR mapping of curved surfaces was developed and interfaced to a diffuse reflectance attachment for an FTIR spectrometer. The device consists of a mounting frame coupled to a micrometer driven translation stage. The sample is longitudinally driven through the focal point of the diffuse reflection attachment. By combining translations with rotations, a two dimensional matrix of spectra from the surface is acquired. The spatial resolution of these spectra approaches 1 mm. A two dimensional mapping of an electrical contact surface reveals an inhomogeneous distribution of a hydrocarbon species (the lubricant) and the presence of a contaminant containing a cyano group.
