To reduce the error at the certification of optoelectronic devices, sources and detectors of the standard sources and its diaphragm must be thermally stabilized in order to create a uniform background. We developed an uncooled model blackbody TCID-100 with working temperature up to 100°C with a thermally stabilized transmitter and the diaphragm set. The developed model is a cylinder made of red copper with a conical cavity. Cone length was chosen empirically to provide uniform heating over the entire length of the blackbody cavity. With the developed model, we conducted cavity temperature measurement transmitter, which enabled to evaluate the advantages and drawbacks of the blackbody design. In this article we examined models of blackbodies, the most popular types of cavities and the calculation of the thermal emissivity for them. We have designed blackbody and measured the cavity temperature change over the time.
