Introducing the usage in planetary exploration as illumination of surface in robotic lunar exploration needs new testing techniques. Commercial LEDs are available in many packages, most SMD mounting and, in many cases, finished with a silicone glob top. The degradation caused by lunar regolith exposure onto all these options is unknown and shall be assessed by testing.

Our Optoelectronics department knows how to fulfill this need. One of our customers requested that we carry a thermal cycling test at extreme temperatures (between 93ºC and -178ºC) over some VIS-NIR calibration sources (five samples at a time). At the same time, these sources were tested in vacuum conditions, and electro-optical characterization at different temperatures during cycling was requested.
