Enhancement in cleanliness and contamination reduction during FPA AIT phase based on non-conformance management

In 30 seconds

The PLATO mission employs rigorous non-conformance management to mitigate particle and molecular contamination on focal plane assemblies. By focusing on the sensitive 81.18 mm square CCD surfaces, the approach ensures optical performance throughout the assembly, integration, and testing phases. This strategy is critical for protecting the high-precision detection chain of 26 telescopes dedicated to exoplanet characterization.
