Paper Abstract

In modern materials analysis it becomes increasingly important to analyze samples at temperatures different from ambient using a variety of analysis techniques. The analysis techniques can be separated into various classes such as 1) transmission 2) direct absorption via photo conductive measurements or reverse energy flow from a warmer detector to a cooler sample 3) reflection at near normal incidence or grazing angle and 4) emission, with particular emphasis on induced emission such as photo luminescence and Raman scattering. The Bomem DA3 FT spectrometer is particularly convenient for the interfacing of a variety of cryostats and other large accessories to the standard, two sample beam, front sample compartment and the new, greatly enlarged, rear sample compartment, which has two sequential sample focus positions. The DA3 now offers a convenient way to switch between sources of radiation and detector modules at the so called input side of the spectrometer. This avoids the need for moving the sample and its accessory, such as a cryostat, between the output side and the input side (emission port) of the spectrometer: all measurement techniques may be performed with the sample and accessory in one position. Operational details and results of measurements will be presented.
