英文摘要	The present invention relates to a thermally insulated optical module. A heat source/sink is thermally coupled with an optical element for sourcing/sinking heat there to/from for temperature regulating the optical element. A thermally insulating packaging forms an enclosure surrounding the optical element. The thermally insulating packaging provides a thermally controlled environment within the enclosure. A thermally conductive structure is disposed within the enclosure and is thermally coupled to the heat source/sink for being temperature regulated thereby. The thermally conductive structure outlines a space surrounding the optical element for providing together with the heat source/sink a second thermally controlled environment therein. The second thermally controlled environment provides a lower temperature gradient across the optical element than absent the thermally conductive structure. Since the optical element is within an environment determined based on dual temperature shielding thereof, adjusting of the temperature at the optical element itself is more easily, accurately, and repeatably performable. For a large range of temperatures outside of the thermal insulating packaging the temperature within the enclosure is adjustable with a known thermal gradient therein. The thermally conductive structure is for sufficiently reducing this thermal gradient within the thermally insulating packaging and, in particular, within the space surrounding the optical element.
