In this paper observed values of emissivity for germanium single crystals with various surfaces received by classical methods of processing (polishing, grinding by the powders F400, F800), and also for the raw surface after a cut. The received values will allow further thermovision researches of germanium single crystals by methods of active thermal control and IR-defectoscopy with minimization of measurement errors.
