Space observatory of millimeter and IR wavelength ranges with cryogenic telescope "Millimetron" ("Spektr-M") with the diameter of 10 m is planned for launch after 2019. Operating range of the telescope is 20 μm to 17 mm. The production technology of its elements is being developed. In the article it is suggested to measure the shape of convex hyperbolic surface of convergent mirror of Millimetron telescope under the conditions of shop floor in the process of shaping and at cryogenic temperatures in the layout of unequal-arm laser interferometer of Twyman-Green type and use computer-generated hologram executed on plane-convex Zerodur blank in the capacity of optical compensator.
