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. Contact us to discuss your application, or learn more about our OEM solutions.

We believe you should have full control and maximum flexibility when configuring an OEM spectrometer for Raman. That’s why we offer multiple configurations with build-to-print options for spectrometer resolution & detector cooling, level of integration, and laser type – backing each with our advice and experience. Contact us to discuss the best options for your application, or explore our full family of Raman products.


SLIT WIDTH: Defining Resolution

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 such as fluorescence. Resolution improves, however, as slit width is reduced (though not always linearly). We offer 10, 25, and 50 μm slits for many of our spectrometers, and can advise on the best choice for your application. 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.


DETECTOR COOLING: Controlling noise

We offer TEC-regulated detectors (standard) and ambient detectors (custom) for our 785 Raman spectrometers for OEMs, allowing you to balance your required signal to noise ratio (SNR) and temperature stability with cost for the best possible value. An uncooled detector serves many OEM applications well and minimizes power draw. For greater noise floor stability in environments with variable temperature, a thermoelectrically cooled (TEC-regulated) detector helps to ensure consistent spectra without the need for frequent dark measurements. Contact us to discuss the right choice for your application.

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, with a choice of detector cooling level to balance dark noise, cost, and power consumption. Need to minimize footprint and power draw for a handheld instrument? Consider our OEM-only single-mode laser option. Contact us to discuss your specific needs.
