Our Partners in Discovery
We collaborate with leading researchers and industries to turn challenges into breakthroughs. From materials analysis to biomedical advancements, our partners trust us to deliver tailored solutions.
Instruments that read materials with light.
Point a laser at a sample and the light that comes back carries two different kinds of information: what the material is made of, and how it behaves. Reading both is what our instruments are built to do — without cutting the sample, staining it, or using it up.

Choosing your depth
How far a laser reaches into a sample is set by how strongly the material absorbs that colour.

crystalline silicon
Choosing a wavelength is choosing a depth — read a surface film or a buried layer, from the same spot.
Approximate penetration depth in crystalline silicon; other materials absorb differently.
Published With Our Instruments
More than 100 peer-reviewed papers have been measured on ProTrusTech instruments. Here are six of the studies we have written up in full.
Analytical Chemistry
When Analytical Chemistry Needed a Raman Reference for Carbon Materials, It Chose Our MRI
An independent journal validated a new IR photoacoustic method against Raman fingerprints taken on our instrument.
Measured on MRI
Biomedical & Diagnostics
One Raman Scan Separates Oral Cancer From Healthy Tissue With 87.5% Accuracy
No biopsy, no stain — a single laser scan.
Measured on ProTrusTech Raman
Materials Chemistry
Catching Nickel’s Most Elusive Intermediate — and Proving It With Heavy Oxygen
The first terminal nickel-oxygen complex on an unsymmetrical ligand, confirmed by 18-O isotope-labelled resonance Raman.
Measured on MRID, 532 nm
Food & Environmental Safety
The 5.5-Nanometre Layer That Turns a Good SERS Chip Into a Femtomolar One
A 5.95×10^8 enhancement factor and a 1 femtomolar detection limit — every result measured on one instrument.
Measured on MRID, 532 nm
Environmental & Water Treatment
Two Metals, One Plating Order — and Nitrate Becomes Harmless Nitrogen Gas
Over 90% selectivity, decided by which metal is plated on top — with operando Raman revealing why.
Measured on MRID, operando
2D Materials
Polarized Raman and PL Reveal the Hidden Axis Powering a New 2D Solar Material
A solar cell built on the axis the scan found reached 5.4x higher efficiency.
Measured on Polarized micro-Raman
Which One Is Yours?
Four platforms, one engineering approach. What separates them is where your sample has to sit, and how faint its signal is.
MRID
Dual Spectra. 360° Polarized. One Click.
Choose this ifyou need two wavelengths on the same micron, or a full 360° polarization scan run automatically.

SRflex
In-Situ. Instant. Field Ready.
Choose this ifthe sample cannot come to the lab — a production line, a reactor, a field site.
Explore SRflex →
NanoSE
See Trace Signals. Build Big Data. Label Free.
Choose this ifthe signal is too faint for ordinary Raman — trace detection from a 10 µL drop.

RAMaker
Big Ideas, Breakthroughs, Made Together.
Choose this ifnothing off the shelf does what you need, and the instrument has to be built around the question.
