• Description:
• Tenders are invited for Truths Phase b2 - Optics Arc (Anti Reflective Coating) TRUTHS (Traceable Radiometry Underpinning Terrestrial- and Helio- Studies) is an Element of the European Earth Watch Programme approved at 178th PB-EO (ESA/PB-EO(2019)31) for submission at CM19+ as a new Element, called “TRUTHS”. TRUTHS (Traceable Radiometry Underpinning Terrestrial- and Helio- Studies - is an operational climate mission, aiming to enhance by an order-of-magnitude our ability to estimate the Earth radiation budget through direct measurements and to establish a ‘metrology laboratory in space- to create a fiducial (International System of units - SI traceable) reference data set to cross-calibrate other sensors and improve the quality of their measurements. The TRUTHS Mission aims at measuring the incoming & outgoing energy from the climate system, including the spectral fingerprint needed to observationally attribute climate processes, with an accuracy needed to detect climate trends in the shortest possible time. The TRUTHS Mission has been authorised as part of the European Earth Watch Programme [ESA/PB-EO(2022)18 rev1] to start its Phase B2/Advance C implementation while authorisation to implement Phase C/D/E1 is subject to the availability of funding and authorisation at C-MiN 2025. Airbus Defence and Space has been selected by ESA as the Prime Contractor for Phase B2 with a mandatory option for Advance C. In this framework, Airbus Defence and Space Ltd will release an Invitation To Tender for the procurement of an optical anti-reflective coating for the TRUTHS Phase B2. The scope of work is to perform a study of multi layered ARC coating operating between 320 nm and 2400 nm and deposited on curved glass substrates to minimise reflectivity considering provided angular ranges, to reduce polarisation sensitivity and to minimise scatter losses. Based on the successful results of this study, it will be requested to coat and test some flat samples using the preferred ARC coating, before and after the operational space environment (i.e. thermo-mechanical and radiation), to achieve TRL 6. Should the results be unsuccessful the work will cease at the end of the study. The Invitation To Tender will be addressed to economic operators (including those deemed to act as Subcontractors) whose registered office is established in such Member and Associated States which, by the time of the Contract award decision, will be a participating State in the ESA TRUTHS Mission. To date, these are: Czech Republic, Greece, Romania, Spain, Switzerland, United Kingdom
