NanoGeoScience has two petrographic optical microscopes as well as others for preparing samples and aligning instruments:
- A Zeiss AXIO microscope (Imager.A1m) for general materials characterization. Several illumination techniques are available: Dark field, bright field and polarized light in both transillumination and epi-illumination. Recently, filters for fluorescence microscopy were added.
- A Leica Polarization Microscope ( DM2500 P) with gypsum plates for identification of minerals based on characteristic refraction properties and colours.
