Infrared Microscopy
The term infrared microscope covers two main types of diffraction-limited microscopy. The first provides optical visualization plus IR spectroscopic data collection. The second (more recent and more advanced) technique employs focal plane array detection for infrared chemical imaging, where the image contrast is determined by the response of individual sample regions to particular IR wavelengths selected by the user.
IR versions of sub-diffraction microscopy (see above) also exist. These include IR NSOM and photothermal microspectroscopy.
