“…In addition, the typical bipod support structure is used to further release the thermal stress between the mirror groups. The PLATO(PLAnetary Transits and Oscillations of stars) 40 , which is being developed by the European Space Agency and will be launched in 2026, is supported by a flexible frame. The next generation facility instrument on the Subaru Telescope, by Japan, is a very wide-field, massively multiplexed, optical and near-infrared fiber spectrograph，known as the PFS (Prime Focus Spectrograph) 41 .…”

Within the ESA PLATO M3 mission, the Telescope Optical Unit (TOU), i.e. the opto-mechanical unit, is a fully refractive optical system. The 26 TOU Flight Models (FM) to be delivered to the upper level, the PLATO Camera, make it a series production. The first Flight Models production faced many initial challenges from a Product Assurance point of view, mostly related to MAIT activities, while moving forward these challenges decreased. Discrepancies and nonconformities associated with, mainly, but not only, materials and processes, cleanliness and contamination control, safety, qualifications and validations, are the object of this proceeding. Thus, showing that serial production adds one more variable to possible failures, but at the same time, when root causes are corrected and solved, yields less difficulties in subsequent FMs MAIT and final production. Product Assurance, in monitoring the product in failure-proofing aspects, aims at mitigating criticalities and arranging for corrective and preventive actions that allow improving the likelihood of success of the mission.

PLATO (PLAnetary Transits and Oscillations of stars) is an M3 medium-class space mission in ESA's Cosmic Vision program devoted to detecting and studying a large number of extrasolar planetary systems. Its launch is planned for the end of 2026 from Europe's Spaceport in French Guiana. The PLATO Payload consists of 26 wide field-of-view Cameras, each observing a specific part of the sky, associated data processing units and power supply units. The 24 Normal-Cameras will provide a very high-resolution photometric measurement of light from a large number of stars, while the other two Fast Cameras will provide the colour information and will deliver the pointing data to the AOCS (Attitude and Orbital Control System). The Cameras will be integrated into an optical bench. Each of them is composed of the Telescope Optical Unit (TOU), the Focal Plane Assembly (FPA) and the Front-End Electronics (FEE). Currently, the serial production of the Cameras has already started facing critical key points, non-conformities and challenging problems. The status of the Product Assurance activities during the serial production for which the first flight models are being delivered after the AIT phase is reported.
