Summary of the contracting process

Diamond Light Source Limited bought an opto-mechanical multiple-mirror system for its B22 infrared beamline at the Harwell Science and Innovation Campus in Oxfordshire. The system is designed to support three synchrotron infrared mirrors, which are not included in the purchase, with motorised three-point kinematic movement. The supply includes design, manufacture and delivery of the mirror system, an ultra-high-vacuum vessel, support structures and fine mechanical alignment adjustments. B22 provides infrared and terahertz radiation for micro- and nanospectroscopy experiments, and also collects visible light for optical alignment. The wider purpose is to equip the beamline as part of Diamond Light Source’s Diamond-II facility upgrade. This is specialist scientific optics and vacuum-compatible equipment, rather than a purchase of standalone mirrors.

The procurement is complete and the contract has been awarded to Instrument Design Technology Limited. The award was made on 2 September 2026 for £228,000 excluding VAT (£273,600 including VAT). The contract was signed on 11 September 2026 and runs from 11 September 2026 to 15 May 2028. The buyer used an open procedure. There was one lot, with an estimated value of £380,000 excluding VAT; three bids reached the final stage, all from SMEs. Evaluation weighted price at 40%, technical quality at 25%, experience and capacity at 25%, commercial matters at 5% and delivery at 5%.

For suppliers who did not win, this award demonstrates Diamond Light Source’s demand for bespoke opto-mechanical systems serving a specialist synchrotron infrared beamline. A credible competitor would need to deliver the integrated design, manufacture and supply of precision mirror-support equipment, including motorised kinematic positioning, an ultra-high-vacuum vessel, structural supports and fine alignment adjustments. The evaluation gave substantial weight to technical quality and to experience and capacity, so evidence of relevant engineering expertise and the ability to execute a technically demanding supply would matter alongside competitive pricing. Delivery and commercial performance also formed part of the assessment. The opportunity was considered suitable for SMEs, and all three final-stage bidders were SMEs, indicating that smaller specialist engineering suppliers can compete for this type of requirement.

Notice Information

Notice Title

9005587 - Supply of B22 Multiple InfraRed Mirror System

Notice Description

Located on the Harwell Science & Innovation Campus in Oxfordshire, Diamond Light Source (DLS) is a leading-edge facility for science, engineering and innovation. DLS allows researchers from academia and industry to investigate the structure and behaviour of the world around us at the atomic and molecular level. To continue delivering the world changing science that Diamond enables, the facility is being upgraded to Diamond-II, a co ordinated programme of development that combines a major machine upgrade with new instruments and complementary improvements to optics, detectors, sample environment and delivery capabilities, and computing, as well as integrated and correlative methods. This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical sciences. Beamline B22 is the InfraRed (IR) beamline of Diamond that will utilize a dipole quadrupole (DQ) magnet as synchrotron source in the new Diamond-II storage ring. The beamline operates 3 end stations, which provide IR and TeraHertz (THz) synchrotron radiation for microspectroscopy and nanospectroscopy experiments. The operational energy range of the beamline is 1 meV to 1 eV (i.e. wavelength range circa 1 ?m to 1 mm). The visible light from the Diamond-II source is also collected and used for optical alignment at B22. The scope of the contract is to design, manufacture and deliver an opto-mechanical multiple mirror system for the InfraRed (IR) beamline B22 of DLS to the performance specifications using a shared concept. The system will support 3 synchrotron IR mirrors (mirrors not part of this tender) designated as Mirror 2a, Mirror 2b and Mirror 2c (M2a, M2b and M2c). Each mirror will have motorised 3-point kinematic motion. The system will have an Ultra High Vacuum (UHV) vacuum vessel, with support structures and fine adjustments for mechanical alignment.
