The NEW WP 785X series is the most comprehensive family of 785 nm Raman spectrometers available. As Raman spectroscopists. we understand that each application is unique. As such, we know that every Raman spectroscopist requires specific configuration options to optimize their research or product development. Solving this unmet need was why the X series was created. We deliver all the features, software, and support you need for Raman:
As the most versatile wavelength in use today, 785 nm Raman has applications in research, security, pharma, and process control. The choice between a flexible, probe-based Raman system and a fully integrated, compact one depends largely upon which optical coupling method is best for your application or sample. Sensitivity, size, and laser control may also be considered. If you have a vision, we have the knowledge & experience to help you create your ideal solution.

We offer two input aperture options, allowing you to balance signal vs resolution for your specific needs. A lower f/# optical bench results in a higher collection efficiency, and thus a higher signal level, so choose our f/1.3 configuration option to get the highest signal spectra. Selecting our f/1.8 configuration option will give you slightly less signal, but will improve the resolution.
We offer a 25 μm slit as standard for the WP 785X 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 two detector cooling options for the WP 785X series to help you to balance your desired signal to noise and thermal stability against power draw and cost for maximum value:
Due to the superior optical throughput of the X series, the majority of users are able to operate at integration times of 1000 ms or less. This makes a TEC-regulated (R) detector suitable for most applications, even for challenging Raman samples. Need advice? Contact us to discuss what’s best for your specific application.

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.

The X series uses a highly configurable optomechanical design that is scalable from 1 to >1000, making it quick & easy to customize to a wide range of applications and use case requirements. By tailoring each spectrometer or Raman system to your unique needs, you get maximum performance at far less weight and cost than with traditional benchtop Raman. These units cover the fingerprint and functional region with <10 cm-1 resolution, making them suitable for most identification, diagnostic, and process applications. Each unit comes with onboard calibration data for spectral response and wavelength, which ensures high spectral accuracy and unit-to-unit reproducibility. We offer several measurement setups, and advice on Raman spectroscopy system design.
Our robust, modular optomechanical design adapts to your unique application needs with options to balance signal and noise with resolution, power consumption, and degree of system integration. Design your own, or let our expertise & testing guide you to the best configuration for your needs. Configuration options include:
We created the WP 785X for emerging OEMs – researchers and instrument manufacturers who are developing innovative new applications of Raman that require a compact module and/or portable Raman spectroscopy system. That’s why we use the same sensitive, robust & highly reproducible optomechanical design for both the laboratory & OEM versions of our WP 785X series spectrometers and systems. This allows you to complete proof of concept and method development with a laboratory 785X series system, then transition directly to the equivalent OEM module for volume production – with no change in performance or need to update your matching libraries or chemometric models. You get the stability and reproducibility of an OEM instrument and research-grade results from day one, and reliable data you can use to build models for use in the field. More ‘OEM Inside’ benefits:

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 785X with regulated (-R) or TEC-cooled (-C) detector.
Need something slightly different? We offer a higher-end line of Raman spectrometers for the most challenging measurements, and OEM modules that are even more compact than the X series for handheld instruments. Consider the option below, or explore our full family of Raman products.
The WP 785X is a unique series of Raman products designed to meet the needs of both researchers and OEMs, based upon a highly sensitive, configurable and manufacturable platform that accelerates an application’s journey from research to reality. At the research/ innovation stage, we get you started with a high throughput, low noise optical bench configured to your exact needs – and reconfigurable for future projects. Then, when you’re ready to take your concept to market, we simply remove the cover. That’s it. No redesign, no model redevelopment, no rework – just speed. We call it ‘OEM Inside’. Let’s take a look:
This unique ‘OEM Inside’ approach allows you to streamline both the instrument design and the product development process, with less risk. You focus on developing your turnkey solution, while we focus on providing superior Raman hardware. Explore our performance-equivalent WP 785X OEM models:

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 wavelengths from 532-1064 nm, matching your specific needs and sample type to the best wavelength for the application.
