## Summary

The Science and Technology Facilities Council (STFC), part of UK Research and Innovation, has completed a procurement process for the supply of large aperture air-spaced achromatic doublets for the EPAC high energy amplifier project. The tender, titled "UKRI-2078 Large aperture air-spaced achromatic doublets", falls under the goods category with a main procurement classification of Optical instruments. The process was initiated through a tender procedure. The contract involves the manufacture, polishing, mounting, optical testing, and delivery of 10 doublets by March 2023 to STFC Rutherford Appleton Laboratory, UK. The procurement stage has been cancelled, with the award already given to Manx Precision Optics.

This tender presents an opportunity for businesses, particularly small or medium enterprises (SMEs), experienced in manufacturing optical instruments to supply large aperture achromatic doublets. The procurement provides a chance for suppliers to contribute to cutting-edge technology in beam magnification and relay imaging telescopes. Businesses capable of meeting the technical specifications and quality requirements outlined in the tender document can consider competing for this contract. The buying organisation, UK Research and Innovation, based in Swindon, United Kingdom, is overseeing this procurement, offering a significant business opportunity within the optical instruments industry.

## Notice

Proposals are sought by the Science and Technology Facilities Council (STFC, who are part of UKRI) for the supply of large aperture, anti-reflection (AR) coated, air-spaced mounted achromatic doublets for use in beam magnification and relay imaging telescopes for the high energy titanium-sapphire amplifier system as part of the EPAC Project. The tender documentation includes the technical specification for the air-spaced achromatic doublets. The Specification should be read in conjunction with the associated drawings. The minimum scope of the contract is for the manufacture, polishing, mounting, optical testing, certification and delivery of the mounted doublets to STFC Rutherford Appleton Laboratory, UK. All technical and quality requirements are described in the tender document that are held in the eSourcing portal. https://www.ukri.org/about-us/procurement-contract-transparency-data/

### Lot Information

Lot 1

Supply of initial quantities of three types of doublets to the specifications detailed with the ability to purchase additional optics at a later date as described in Section 15 of the specification. A schematic diagram outlining the general design characteristics of each air-spaced mounted doublet is shown in Figure 1 of the specification. It consists of a pair of circular lens elements, referred to as ELEMENT A (negative meniscus) and ELEMENT B (positive meniscus), each of centre thickness Z thick, and separated by an air-gap (Z gap). The faces of each lens element are referred to as F1 to F4. Individual lens elements will be secured independently within a frame of fixed outside diameter providing a minimum clear aperture for optical transmission of a high energy laser beam. There is an initial total of 10 doublets to be procured and delivered by March 2023, however, earlier delivery is preferred. Please refer to the Delta eSourcing portal link for the full details and specification. https://www.ukri.org/about-us/procurement-contract-transparency-data/ Additional information: To respond to this opportunity please click here: https://ukri.delta-esourcing.com/respond/5BNDC23ZUY

Options: Further quantities may be purchased at a later date, as stated in the ITT document.
