Design, production, verification and delivery of the ELT M1 segments Local Coherencer

Preliminary Inquiry (PI) to identify and select companies that are interested in and capable of designing the ELT M1 segments Local Coherencer, delivering one Validation Model during the design phase, and producing six European Organisation for Astronomical Research in the Southern Hemisphere Page 2 measuring heads mounted on a supporting structure, to be attached to the “M1 segment manipulator” (see related Advance information No. 207). The Local Coherencer is a non- contact metrology system, which consists of 6 measuring heads which optically sense with nanometer accuracy the relative height of an hexagonal segment with respect to its (up to) 6 neighbours. The PI will be released in Q3/2020 to potential suppliers in the ESO Member States and Chile and will be followed by a Call for Tender (CFT) planned to be issued in Q4/2020. The contract is expected to be awarded in Q2/2021 to the Bidder, which has submitted a fully compliant Tender and offers the best value for money for ESO taking into account the quality and price of the offer.
