We have the broadest selection of moderate to high performance OEM Raman systems and accessories on the market. These modules vary from DIY to completely integrated systems. Starting with our DIY systems choose three visible to NIR modules from blue to NIR laser excitation.

Is fluorescence interfering with your Raman?  Choose our Sol™1.7 1064 nm laser package. We also offer one of the world’s smallest pre-configured, pre-packaged, fully integrated 785 nm OEM Raman modules in our SAVANNAH™ system with orbital Raster Scanning (ORS).


Are you exploring the realm of what Raman can do for you?  Our DIY building blocks have the flexibility of arranging key components using light travel via fiber optics starting with laser, spectrometer, sampling probes/cuvette holders which are assembled on our base breadboard platform. 

Choosing a System 

Stay near the visible green to take advantage of the scattering sensitivity where signal and excitation wavelength are related as 1/λ4, and less laser power may be required to minimize heating on solid surfaces. Move further into the near infrared to eliminate competing background fluorescence. 

Contact our Application Specialists to help choose the best system for you.


The Discover-It-Yourself series from Metrohm Spectro is designed to help develop new Raman applications and explore samples your way. The Extended Range DIY system (DIY-ER) is unique because it measures the Raman spectrum in stretch and fingerprint regions using a single detector and two laser lines. The software then “stitches” the two spectra together to give you the complete Raman spectrum with easy sampling. Overcome challenges with fluorescence interference using the DIY-ER.


Pre-optimized tiers of spectrometers are available for the UV-VIS system. Each tier is built with your application in mind with proper sampling and light source recommendations. The spectrometers are all designed with important parameters like Stray Light and Quantum Efficiency in mind to ensure value from entry level to high performance systems.

DIY Low Frequency Raman System

The Low-Frequency DIY system (DIY-LF) is unique because it measures the Raman spectrum on the anti-Stokes region, across the laser excitation line, and into the Stokes region. Powerful filters remove scattering within about 5 cm-1 of the laser line to give you access to structural Raman data that is unavailable through other techniques.

An array of sampling accessories is compatible with the probe, extending its' capabilities. Low Frequency Raman opens a new spectral window, giving you an opportunity to find new answers you didn't even know existed.


SAVANNAH is Metrohm's most compact OEM Raman module. The SAVANNAH is equipped with an integrated 100mW 785nm single mode laser, and a high-performance spectrograph with a spectral range of 400- 2300 cm⁻¹ and resolution of < 10 cm⁻¹.

The unique Orbital Raster Scanning (ORS) feature minimizes laser ablation/heating and reduces sample heterogeneity effects. The robust architecture and small footprint makes SAVANNAH perfect for integration into handheld, mobility and point-of-care instrumentation.
