This article presents the impact of thermal radiation of the internal elements of the camera on temperature and its distribution on the bolometers of the Focal Plane Array. In order to estimate the effect of this component, a simplified radiation heat transfer model was created for the detector, the object and the camera housing. The model is based on the known term of radiation configuration factors. It was also suggested to use a radiation screen to isolate the detector from the influence of the camera housing. Finally, results of numerical simulations for different camera work conditions are presented.
