| Main Category: | Goods |
| Procurement Method: | Award procedure without prior publication of a call for competition |
| Method Rationale: | This is a voluntary ex ante transparency notice (VEAT). This notice is to indicate that the University intends to contract with Cambridge Raman Imaging SrL for the purchase of a Stimulated Raman Laser & Multi-Channel Lock-In Amplifier consisting of the following: Key features of the Stimulated Raman Laser 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 ≤ 1 nm, Stokes ≥ 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 × 390 × 395 mm; Embedded control and power electronics Key features of the Amplifier 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: 0–360° in 32 steps per channel; Shot‑noise‑limited acquisition down to ~25 µW per channel; Noise‑equivalent power (NEP): < 20 pW/√Hz; Fixed filter time constant: 0.5 µs; 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. |
