This contract falls under the category of optical instruments and is valued at £288,000. The procurement method is an open procedure, and the tender period closes on 23rd June 2022, with bid submissions to be delivered to their facility in Oxfordshire by the specified deadline. Technical specifications and additional details can be accessed through the Delta eSourcing portal. This tender presents significant opportunities for businesses, particularly small and medium enterprises (SMEs), to engage in the supply of optical components essential for advanced scientific projects. Firms specialising in optical manufacturing, precision engineering, and testing services would be well-suited to compete for this contract, which also provides a potential for future orders as described in the tender documentation. This is an excellent chance for companies to expand their involvement in government-funded research projects and enhance their operational capabilities in the optical 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. ### 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.
