## Summary

Heriot-Watt University, located in Riccarton, Edinburgh, is undertaking a procurement process for the purchase of a Stimulated Raman Laser and Multi-Channel Lock-In Amplifier designed for research purposes. This contract falls under the education industry category and is governed as a body by public law. The process is at the stage of award and contract signing, having completed the voluntary ex ante transparency notice (VEAT) without prior call for competition due to the lack of other suitable suppliers. The contract was awarded to Cambridge Raman Imaging Srl on 22nd April 2026, with a total contract value of €168,000. The equipment is set to be delivered to the Heriot-Watt University, Riccarton Campus, Edinburgh, EH14 4AS.

This procurement presents a distinctive opportunity for growth in the specialised field of research-focused technological innovation, particularly benefiting suppliers like Cambridge Raman Imaging Srl with niche expertise in advanced laser systems and spectroscopy equipment. Suitable businesses are likely those positioned within the optical technology and scientific instrumentation sectors seeking collaborations with educational institutions for cutting-edge research applications. The equipment, characterised by its high spectral resolution and rapid data acquisition capabilities, underlines a strategic commitment to advancing research infrastructure at Heriot-Watt University.

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.
