## Summary

Heriot-Watt University, located at Riccarton Campus in Edinburgh, UK, has completed the procurement process for acquiring a Stimulated Raman Laser and Multi-Channel Lock-In Amplifier, primarily intended for research purposes. The procurement was conducted without prior publication of a call for competition, as indicated in a recent Voluntary Ex Ante Transparency Notice (VEAT) published on 29th April 2026. The purchasing process falls under the category of laboratory, optical, and precision equipment, with classification CPV code 38000000, focusing on goods. Though the tender status is marked 'complete', no award has been made due to its unsuccessful status. The standstill period is in place for ten days to allow for transparency before any potential award. The procurement method was limited due to a lack of suitable tenders available under open procedure.

This tender presents robust growth opportunities for businesses specializing in advanced optical and laboratory equipment. Companies that excel in producing high-quality Raman Laser systems or multi-channel lock-in amplifiers with cutting-edge technical specifications would be particularly well-suited to participate in such procurement processes. Furthermore, suppliers with unique technological offerings, like Cambridge Raman Imaging Srl, who was involved in an active contract signed on 22nd April 2026, could benefit from leveraging their niche expertise to secure similar contracts, especially given the absence of market alternatives for specific equipment requirements. Participation in future VEAT notices or similar limited procurements may also offer potential business expansion avenues in the public sector research domain.

## Notice

Purchase of Stimulated Raman Laser & Multi-Channel Lock-In Amplifier for research purposes

### Lot Information

Lot 1

The University requires to purchase from supplier-Cambridge Raman Imaging SrL the following: STRALE - laser system for broadband stimulated Raman scattering (SRS) in a full CH-stretching region detected in a single shot, with no need for sequential tuning of the emitted wavelengths, while preserving high spectral resolution. Key features of the system: Integrated pump beam modulator: modulation frequencies from 1 to 10 MHz Central wavelengths: pump 792 nm +- 1 nm, Stokes 1030 nm FWHM spectral width: pump = 30 nm Output power: pump > 70 mW @ 1-10 MHz modulation; Stokes > 180 mW @ 20 MHz rep. rate Pulse energy: pump > 7 nJ, Stokes > 9 nJ Pulse width: pump < 2 ps ; Stokes < 0.2 ps Wavenumber coverage [cm-1]: 2800-3100 (full CH-stretching region) Wavenumber resolution [cm-1]: < 16 Synchronized dual output Air-cooled, compact footprint: 610 x 390 x 395 mm Embedded control and power electronics CHAMP - multichannel lock-in amplifier spectrometer is an optical spectrometer based on CRI proprietary multi-channel lock-in technology, ensuring extremely low electronic noise levels, high spectral resolution and short integration time. It has been designed to detect tiny variations, as small as one part over 10 millions, in few microseconds. A unique solution on the market for pixel-wise broad vibrational spectra reconstruction at megahertz modulation frequencies. Key features of the spectrometer: 38 lock-in amplifiers with independent AC (demodulated) and DC (average power) outputs Triggerable integration-time averaging up to 30 ms Demodulation frequency range: 1-10 MHz Demodulation phase: 0-360deg in 32 steps per channel Shot-noise-limited acquisition down to ~25 uW per channel Noise-equivalent power (NEP): < 20 pW/Hz Fixed filter time constant: 0.5 us Vertical resolution: 16 bit Spectral resolution: < 9 cm-1 * Real-time demodulated-signal normalization Pixel- and line-triggered synchronized acquisition USB 3.0 PC connection for fast data transfer Two additional analog inputs and outputs for PMT acquisition Following market research carried out by the academic research team, there are no other suppliers available in the market to supply this type of equipment in the form factor required. The principal purpose of the contract is to acquire goods in connection with research undertaken by the University.
