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 SYSTEM
A 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 785XM 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 785XM 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?

Our Raman spectrometers are far more sensitive and higher throughput than the average compact spectrometer – to give you better spectra in less time. We’ve made them robust & reproducible enough to give reliable answers in the lab, the field, or the hospital. We offer more configurations than any other Raman spectrometer provider, and help you to find the right fit through our expertise & experience, supported by Raman-specific software tools with full data transparency so that you have full control over data analysis. We care enough to listen to our customers and respond, and we will listen to your needs to help you get the best solution possible.

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.

Need something slightly different? We also support custom optical designs & integration with customer electronics upon request. Contact us to discuss your unique application and customization options.
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 785XM with regulated (-R) detector.
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. Consider the option below, or explore our full family of Raman products.
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? Read our tech note, Choosing your Raman excitation wavelength, or contact us for a personal consultation or sample testing.
