FIELD: measurement equipment.
SUBSTANCE: invention relates to thermal physics and may be used to determine extent of blackness of the surface of composite and thin-film materials. The method is based on application of sample surface heating and registration of radiation temperature from the sample with coating and available value of blackness extent and from the sample without coating. The proposed solution provides for localisation of the measured section area by means of a special screen from noise impact, and also creation of a local heating area, stable by temperature and area from a special source of heat of directed action. Also application of an IR-mark is provided for preliminary identification of thermal field parameters and operation with least losses.
EFFECT: increased validity of material surface blackness extent determination.
