WP 532X Raman Spectrometer Series

The NEW WP 532X series is the most comprehensive family of 532 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:

  • High NA, f/1.3 optical design for best-in-class sensitivity or f/1.8 design for higher spectral resolution
  • Scientific grade detectors: regulated to 10ºC (high QE) or cooled to -15ºC (lower noise)
  • Two robust, thermally stable form factors: certified lab-ready units or equivalent OEM engines
  • Replaceable slits to allow tradeoff between optical throughput and spectral resolution
  • 270 – 4700 cm-1 measurement range, < 11 cm-1 resolution
  • Open-source ENLIGHTEN™ software & SDKs for Raman

Complete Your Raman System

As the most popular Raman wavelength for inorganic samples, 532 nm Raman is often used to analyze carbon nanomaterials, semiconductors, metal oxides, minerals, and gemstones – as well as being used in resonance Raman experiments and SERS (surface enhanced Raman spectroscopy). A flexible, probe-based Raman system works well for many of these, particularly with our user-configurable Raman probes, which can adapt to different types of optical systems and samples. If you have a vision, we have the knowledge & experience to help you create your ideal solution. 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.

Note: Specifications are subject to change based on available components & manufacturing data.


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 532X 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 532X series to help you to balance your desired signal to noise and thermal stability against power draw and cost for maximum value:

  • TEC-regulated (-R): Detector is cooled externally to 10 ± 0.2°C (See right, top plots)
  • TEC-cooled (-C): Detector has integrated cooling to -15 ± 0.2°C (See right, lower plots)

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.

X series benefit #1: Configurable design, comprehensive options

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.

X series benefit #2: Full spectrometer customization

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:

  • System configuration: spectrometer only (IC) or OEM equivalent on a baseplate
  • Sample coupling: external fiber optic Raman probe vs integrated probe (learn more)
  • Input aperture: f/1.3 input to collect more signal, or f/1.8 input to achieve better resolution
  • Detector cooling level: temperature-regulated detector (10°C) or TEC-cooled detector (-15°C) (learn more)
  • Slit size: 25 µm is standard, 15 µm & 50 µm custom

X series benefit #3: OEM-ready to accelerate your product development

We created the WP 532X 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 532X series spectrometers. This allows you to complete proof of concept and method development with a laboratory 532X 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:

  • Configurable, scalable modules and Raman spectroscopy systems, at volumes of 1 to >1000
  • Transition easily and confidently from research to product development
  • Programmer-friendly, open-source software & SDKs in multiple languages, GitHub access
  • OEM partnership & consultation, from product design to volume production
  • Faster time to market with less surprises
  • Ideal for point-of-use instruments in the field, the lab, the clinic, and industry

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 532X with regulated (-R) or TEC-cooled (-C) detector.

Alternate System Configurations

785 nm Raman
830 nm Raman
1064 nm Raman

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.
