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.

IFMIF-DONES is a critical facility in the roadmap toward commercial fusion energy dedicated to studying materials under extreme neutron irradiation for the future DEMO (fusion electrical energy plant). IFMIF-DONES will consist of a deuteron linear accelerator where the deuterons collide with a molten lithium target and generate a neutron beam that will irradiate DEMO materials.

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).

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.
