Complete Your Raman System

Upgrade your current Raman setup with this sensitive standalone spectrometer, or build a new system from the ground up. Either way, you’ll have maximum configurability in choice of laser and sampling optics, and control over resolution and signal level with our user-interchangeable slit.

Make it a complete, fully modular Raman setup:
• Add a 532 nm laser and our unique user-configurable probe or your own sampling optics
• Switch between liquid and powder samples with a multipurpose sampling chamber
• Install our free ENLIGHTEN™ software or use our SDKs to write your own code
• Receive a complimentary 1-year KnowItAll licence to perform Raman libary matching

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

Detector Cooling Options

We offer three detector cooling options for the WP 532 Raman spectrometer, allowing you to balance your desired signal to noise and temperature stability against power draw and cost for maximum value:

  • Ambient (-A): No detector cooling; follows temperature of environment
  • TEC-regulated (-R): Detector is cooled externally to 10°C
  • TEC-cooled (-C): Detector has integrated cooling to -15°C

Competitive Advantage

We’ve made it our mission to design compact, portable Raman without compromise – instruments that deliver superior sensitivity at a cost-effective price point. We place one of our own perfectly matched, patented volume phase holographic (VPH) gratings at the heart of every spectrometer. With uniform response and low loss, these gratings enable a compact and highly efficient all-transmission optical design that minimizes loss and maximizes stability for consistent, high-SNR spectra.

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.

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 248-1064 nm, matching your specific needs and sample type to the best wavelength for the application. Explore our alternate wavelengths below.
