Abstract
An ATR objective () for an IR microscope has a Cassegrain objective (), an ATR crystal (), a holding bar () to one end of which on the side of the sample, the ATR crystal () is mounted, a holding element (), thin struts () which rigidly connect the holding bar () to the holding element () and intersect an optical path of the ATR objective () entering or exiting the Cassegrain objective () in such a fashion that they shade less than 10% of the beam cross-section of the optical path, and a motor drive () for axial movement of the holding element () relative to the sample position (). The automated ATR objective thereby enables simple adjustment of operating modes and different contact pressures of the ATR crystal with respect to a sample ().
