Title: Development of the mid-infrared camera for the 2.5-m Telescope of the Caucasus Mountain Observatory of SAI MSU and the study of circumstellar dust shells of late type stars.

Abstract: The report describes the mid-infrared photometer created on the basis of a commercial detector and the developed procedure of data reduction from the near-infrared camera of the 2.5-m CMO SAI MSU telescope. The results of the investigation of the possibilities of the infrared instrumentation of this telescope are presented. The catalog of SED stars at late evolutionary stages observed by the ISO space observatory, which we have created, is given. In the example of several stars, the process of building models of their dust envelopes is presented.
