Abstract
An auxiliary device enabling reflection measurements to be carried out by an IR spectrometer designed for the performance of transmission measurements comprises two deflecting mirrors (22, 23) to be positioned in the straight beam section of the spectrometer and two focussing reflector arrangements (26, 2, 27) of which the first forms at the location of the sample (16) to be investigated by the reflection method a reduced image of the focus (30) situated within the ray of beams (28) deflected by the first deflecting mirror (22) while the said second focussing reflector arrangement forms an enlarged image of the said reduced focus at a distance before the said second deflecting mirror (23) so that the beam of rays (33) emitted by the said second deflecting mirror forms a prolongation of the beam of rays inciding upon the said first deflecting mirror just as if the auxiliary device did not exist. Each reflector arrangement comprises a collimator mirror (26, 27) for parallelizing the divergent beam of rays emitted by the associated deflecting mirror (22, 23) and sections of a common parabolic mirror (2), the beams of rays (29, 31) emitted by the said collimator mirror (26, 27) extending in parallel to the axis of the said parabolic mirror (2) and the sample being arranged at a point coinciding with its focal point (16).
