High throughput and robust spectrometer modules for OEM integration

The ROCK VIS spectrometers offer the market’s highest throughput industrial grade spectrometers. These benefits are accomplished by our highly efficient in-house manufactured transmission gratings and a high numerical aperture 0.22 (f/2.2) nearly on-axis beam geometry in the optical bench.

The ROCK VIS spectrometers enable better sensititvity and/or lower optical light input power than traditional spectrometers.

Key features

  • 380 to 770 nm wavelength range
  • Numerical aperture of 0.22
  • Typical resolution of 2.0 nm (FWHM)
  • Signal-to-noise Ratio up to 10000:1 with NMOS detector
  • Symmetrical peak shapes
  • Athermal optical bench


  • RSV-200 and RSV-220 – for high dynamic range and S/N (up to 20000:1 and 10000:1, respectively)
  • RSV-300 – for high sensitivity and cost efficient designs
  • RSV-305 – for high sensitivity and medium S/N
