SUMMARY The application of microscope photometry in non‐biological fields is reviewed. The objects in microscope photometry are micro‐particles or small areas of macro‐scopical bodies which, because of their size, cannot be examined by macrophotometry. The commonly measured properties in microscope photometry are as follows: transmittance, specular or diffuse reflectance, relative intensity of light emission by self‐luminous objects, e.g. luminescence or fluorescence, in the spectral (wavelengths) range ca. 250–1000 nm. The paper gives examples of how coloured solid bodies, e.g. gemstones and ore minerals, can be identified, rock‐forming minerals differentiated, diamonds classified, paper quality assessed, organic constituents in rocks characterized, crime detection aided, the chemistry of alloys established, and information on structural organization in inorganic and organic crystals supplemented.
