Paper Abstract

At the Osservatorio Astronomico di Brera we are developing new technologies for the construction of low-weight X-ray optics based on Silicon Carbide and Alumina. The low-density of these materials in addition to their good mechanical characteristics can allow not only to fit the weight requirements but also to get a high angular resolution. The technique under development is based on the production of a ceramic carrier onto which it is epoxy replicated an Au layer previously deposited on the superpolished surface of a mandrel, the mandrel profile having the negative shape of the mirror optics. The bulk material of the mandrel is aluminum while its external surface is given by a thin layer (100 microns) of electroless Nickel. In the present paper we will describe very encouraging progresses that we recently obtained and we will propose this technique for the optics realization of future space projects.
