Abstract
A system including an optical system having at least one refractive or reflective element, the optical system configured to substantially receive electromagnetic radiation emanating from a source, the optical system being located within a Dewar, a support structure, support structure being mechanically disposed between the optical system and a surface of the Dewar, the support structure having substantially low thermal conductance, a cold source; the cold source being located within the Dewar, a thermal link, the thermal link being mechanically disposed between the optical system and the cold source, the thermal link being substantially flexible and having substantially high thermal conductance.
