WP248 Raman Spectrometer


Eliminate fluorescence with this compact, high sensitivity 248 Raman spectrometer for research. Designed for use with a 248.6 nm compact NeCu laser in a free-space configuration, it also enables cost-effective application of UV resonance Raman.

  • Ideal for fluorescence-free research & UV resonance Raman
  • 400 – 3200 cm-1 measurement range enabled by our custom longpass filter
  • Captures clean spectra in seconds (see example spectra below)
  • Collects a collimated FOV using integrated lens (user-changeable free space input available)
  • High NA, f/2.0 design based on our own VPH grating for superior sensitivity
  • Choice of uncooled or TEC-regulated detector to suit application needs
  • Triggering accessory included to synch acquisition with laser
  • Complimentary ENLIGHTEN™ operating software & SDKs


The WP 248 Raman spectrometer may be configured with your choice of sample coupling (integrated lens or free space). Our standard option is an integrated lens designed to efficiently couple collimated light into the f/2.0 spectrometer input. We also offer a free-space input, which is user-exchangeable in the field. The spectrometer is designed for use with a Photon Systems 248.6 nm NeCu laser, and includes a compatible triggering accessory. Need help designing your free-space sampling optics?

We offer two cooled detector options for the WP 248 Raman spectrometer, allowing you to balance your desired signal to noise and temperature stability with power draw and cost for maximum value. Not sure what’s right for you? Contact us to discuss.

-A detector: Operates at ambient temperature,  typically 25°C (uncooled); suitable for many applications
-R detector: TEC-regulated to 10°C; most cost-effective Raman solution
