  Optical coherence tomography (OCT) is a high-resolution three-dimensional
imaging technique that enables non-destructive measurements of surface and
subsurface microstructures. Recent developments of OCT operating in the
mid-infrared (MIR) range (around 4 {\mu}m) lifted fundamental scattering
limitations and initiated applied material research in formerly inaccessible
fields. The MIR spectral region, however, is also of great interest for
spectroscopy and hyperspectral imaging, which allow highly selective and
sensitive chemical studies of materials. In this contribution, we introduce an
OCT system (dual-band, central wavelengths of 2 {\mu}m m and 4 {\mu}m) combined
with MIR spectroscopy that is implemented as a raster scanning chemical imaging
modality. The fully-integrated and cost-effective optical instrument is based
on a single supercontinuum laser source (emission spectrum spanning from 1.1
{\mu}m to 4.4 {\mu}m). Capabilities of the in-situ correlative measurements are
experimentally demonstrated by obtaining complex multidimensional material
data, comprising morphological and chemical information, from a multi-layered
composite ceramic-polymer specimen.
