Wasatch Photonics 785nm Raman Spectrometer System



WP 785 Raman – SET

Compact f/1.3 Raman spectrometer with a grating stabilized 785nm laser and a fiber optic probe. The Wasatch Photonics Raman spectroscopy system comes complete with everything you need including a sample cuvette & vial holder and software.

  • Excellent quality data, benchtop performance yet at a “compact” price
  • Exceptional speed, up to 30x faster measurements largely due to the proprietary f/1.3 optics
  • Superior stray light suppression, which results in higher SNR
  • Trace-level limits of detection possible even without deep cooling of the detector
  • High thermal stability of the grating and bench design leads to reproducible, accurate results
  • Fiber-coupled Raman probe has built in filters and focusing optics for through-container, standoff and contact sampling
  • ENLIGHTEN™ spectroscopy software – included free!

Volume Phase Holographic Grating provides optimum throughput and a simpler optical design….

SLIT WIDTH: Defining Resolution

Sensitivity and resolution are competing factors when choosing slit size. A larger slit allows more light to enter the spectrometer while increasing sensitivity for low-light applications such as fluorescence. Resolution improves, however, as the 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.

We have specified our 25um slit for best resolution, but you can change to 50um or 10um when you order a system. Be sure to contact us to discuss your application.
