    Abstract: A space optical instrument is disclosed including a primary mirror having an optical axis and including a first face, referred to as the front face, oriented towards an observed area, and a second face opposite to the first, referred to as the rear face, the optical instrument further including a thermal stabilization device for the primary mirror, comprising a thermally conductive wall extending around the optical axis (O) on the front face side of the primary mirror towards which this face is oriented. The thermal stabilization device further includes a temperature regulating device for the circumferential wall that is capable of using the measurement of an incident heat flux on the mirror, and adapting the temperature of the circumferential wall according to the measured incident heat flux, in order to keep the front face of the mirror at a constant temperature.

    Abstract: An improved mount for, and method of mounting an, optical structure is provided. The mount has an optical structure comprising at least one mirror panel, the mirror panel comprising a reflective surface and a back surface substantially opposite the reflective surface, a protruding member extending from the back surface of the optical structure, the protruding member having a shape and the shape having an outside surface there-around, a base comprising a mounting element and an upper element extending from the mounting element, the upper element having a cavity for secured receipt therein of at least a portion of the protruding member, wherein the receiving cavity of the upper element has a shape identical to that of the shape of the protruding member, but where the shape of the protruding member is ten thousandths ( 1/10,000) of an inch smaller than the shape of the receiving cavity so that the outside surface of the protruding member is ten thousandths ( 1/10,000) of an inch away from the corresponding parts of the receiving cavity when the protruding member is secured within the cavity.
