Axetris Infrared Sources ready for take-off to Mercury


Source: Axetris Ag

Axetris infrared sources are built into the MERTIS IR Spectrometer as part of European Space Agency’s BepiColombo Mission.

The Electrically Modulated Infrared Sources (EMIRS200) from Axetris were chosen due to their black body emission characteristics. Long lifetime and emission stability are key strengths of the MEMS-based design. The MERTIS spectrometer will operate in the 7-14 mm wavelength range for detecting elemental signatures of minerals such as feldspars, elemental sulfur, and other rock-forming minerals abundant on Mercury.
