Abstract
An IR microscope (1) is constituted such that, in an optical viewing mode in a beam path of visible light (VIS-R, VIS-T), a first intermediate focus (ZW1) is imaged onto a flat detector surface (15a) of a camera. The IR microscope (1) is constituted such that, in the beam path of the visible light (VIS-R, VIS-T), the first intermediate focus (ZW1) is imaged onto a second intermediate focus (ZW2), and, in the second intermediate focus (ZW2), a Mangin mirror (11) is disposed that corrects a field curvature of the Cassegrain objective (4). The invention provides an IR microscope in which the field curvature generated by the Cassegrain objective is corrected in a simple manner in the optical viewing mode when detection is performed using a flat detector and without restricting the spectral range of the IR microscope.
