Typical pass/fail criteria are not useful while no actual information about optoelectronic parts (mostly COTS) are operated in space environments or sometimes in ways for which were not designed. Detailed study of the degradation or failure modes may determine that not fully compliant devices may still be suitable for a certain application.

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.

Thermal Vacuum Testing is necessary to be carried out because the environmental conditions in the space are extreme, the combination of low pressure and extreme temperatures can cause the failure of a component. That is why in Alter Technology, we test the components in similar conditions.

Space agencies have carried out numerous research projects to develop systems to detect and quantify the concentration of Greenhouse gases, such as carbon dioxide and methane, which are the main drivers of climate change. The measurement system used for this purpose is called LIDAR (Light Detection and Ranging).

A compact and cost-effective NIR-VIS-UV lidar echo emulator (LEE) was designed and manufactured as a compact breadboard. The LEE is an application-specific optical pulse shaper delivering a short lidar return (echo) in the ns range overlapped with a long lidar return in the µs range with a repetition rate from 100 Hz – 500 Hz. The short echo power levels are in the range from 0.2–200 nW, whereas the long echo powers are from 0.1–25 pW.
