Abstract : The patent concerns an optical device comprising a glassy material which exhibits temperature-dependent optical absorption properties. The intensity of radiation beams which are transmitted through the material is thermally controlled so that the device can attenuate, modulate, or become opaque to the transmitted radiation. The preferred material is Tl2SeAs2Te3.
