Complete Your Raman System

These powerful, highly compact OEM Raman spectrometers have been deployed in a wide range of applications, each one carefully & collaboratively configured to offer the best value for the task at hand. Standard configurations include spectrometer only, spectrometer + laser, or fully integrated spectrometer + laser & sampling optics. Need to minimize footprint and power draw for a handheld instrument? Contact us to discuss your specific needs, or learn more about our system configuration options.

FULLY MODULAR SYSTEMA fully modular Raman system uses fibers to route excitation light between laser, probe, and spectrometer. This is ideal for bringing Raman to the sample.

We offer an f/1.3 optical bench for the XM series to maximize collection efficiency for the highest signal spectra.


We offer a 25 μm slit as standard for the WP 830XM series, and 15 & 50 μm slits as options to achieve better resolution or more throughput, respectively. Sensitivity and resolution are competing factors when choosing slit size. A larger slit allows more light to enter the spectrometer, increasing sensitivity for low-light applications. Resolution improves, however, as slit width is reduced (though not always linearly). Due to the high sensitivity of our low f/# spectrometer designs, it is often possible to use a smaller slit width than would be required with a typical f/4 spectrometer, allowing you to achieve higher resolution.


We offer A TEC-regulated (-R) detector cooled externally to 10 ± 0.2°C for the WP 830XM series. This achieves high signal to noise and good thermal stability at reduced power draw and cost for maximum value. Due to the superior optical throughput of the XM series, the majority of users are able to operate at integration times of 1000 ms or less, even with challenging Raman samples. Need advice?

We are an experienced OEM partner

At Wasatch Photonics, we’ve built a team that understands the needs of OEM customers, and a spectrometer bench that exceeds them. Our OEM Raman spectrometers are robust, compact, and easy to integrate, yet deliver the same outstanding sensitivity of our standard laboratory instruments. Our transmission optical bench is designed with diffraction-limited optics, achieving an optimum balance of throughput and resolution across the fingerprint range, with alignment that remains stable across temperature and in the harshest environments. Consistency, reliability, and value are key when you’re designing a product to be built in volume and deployed in the real world, and we deliver – in performance, in expertise, and in the quality of our service. Learn more about our OEM philosophy, capabilities, and support

Common Raman Spectral Bands

The pattern of peaks in a Raman spectrum is unique to the sample, providing a fingerprint which can be used to identify or analyze the material. The ‘fingerprint’ region up to 1500 cm-1 is often enough to confirm identity, while the extended ‘functional’ region out to 3600 cm-1 includes bands for additional, functional groups in a molecule. In addition to our standard models, we can design custom range spectrometers for OEMs. See below for common Raman spectral bands and how they compare to the range of the WP 830XM with regulated (-R) detector.

Alternate System Configurations

Need something slightly different? We offer a higher-end line of Raman spectrometers for the most challenging measurements, and a mid-range series that covers the functional band in a slightly larger footprint than the XM series.

Choosing the right Raman wavelength for your application is a question of balancing sensitivity and selectivity. Although shorter wavelengths deliver the strongest Raman signal, fluorescence background can degrade signal-to-noise ratio (SNR) if the wrong wavelength is used. That’s why we offer multiple excitation wavelengths, matching your specific needs and sample type to the best wavelength for the application. Click on the buttons above to explore our alternate wavelengths. Still unsure of what you need?
