Mars Rover "Curiosity"

ifw optronics supplies the SiC UV-detectors for the successful NASA Mars mission "Mars Science Laboratory" with the landing-rover "Curiosity". As a part of the rover weather-station (REMS) SiC photodiodes work reliably since over 2000 sols and detect the UV radation on the Mars surface in five different wavelegth ranges.

 

We used large-area SiC-chips with our standard and custom filters and an assembly technology fitted to the low temperatures. Circular permantent-magnets around the photodiodes prevent increased deposition of the iron contaning mars-dust. The area in the center of the diodes serves as reference for the absolute contamination of the sensors.
