Ibsen PEBBLE NIR Spectrometers

Ultra-compact (less than 1-inch envelope) and cost-efficient OEM spectrometer modules for the near-infrared range


The PEBBLE NIR spectrometers offer a cost-efficient mini spectrometer module for OEM manufacturers of analytical instruments that do not want to sacrifice performance and robustness for compactness.


This type of multi-spectral sensor in the NIR range provides many benefits when used in the agricultural, pharma, and medical industries. It can detect gluten, diffuse tissue reflectance, and blood analysis. The PEBBLE spectrometer is small and thus good for handheld devices. The compact spectrometer is also easier to use and provides the full spectrum.


The miniature PEBBLE NIR spectrometer covers a wavelength range of 950 – 1700 nm and offers a resolution of 12 nm. It utilizes a sensitive un-cooled G13913 InGaAs detector from Hamamatsu.


Key Features:


  • 950 nm to 1700 nm wavelength range
  • Numerical aperture of 0.22
  • Configurable resolution from 12 nm to 16 nm
  • Footprint of 23 mm x 21 mm x 8 mm
