Ultra-compact 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.

PEBBLE NIR is based on the same proven diffraction grating technology used in all other Ibsen spectrometers. This ensures that PEBBLE can be manufactured in high quantities with very small unit-to-unit performance variations.

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.

If the specifications of our standard PEBBLE configurations do not match your requirements, Ibsen can customize an OEM spectrometer to meet your exact needs.

Key features:

  • 950 nm to 1700 nm wavelength range

  • Numerical aperture of 0.22

  • Resolution: 12 nm (typical)

  • Fast and sensitive InGaAs detector array with 128 pixels

  • Electronics interface: small flex-connector

  • Optional SMA – or free space adapter

  • Compact footprint of 23 mm x 21 mm x 8 mm

Performance comparison of mini spectrometers

Research Center for Non-Destructive Testing GmbH – RECENDT, has conducted a report, comparing our PEBBLE NIR to a similar reference spectrometer. The comparison is among other aspects on the specs, signal to noise, and sensitivity, where PEBBLE, despite its tiny footprint performs quite well.

How to couple into your spectrometer

You can couple into your spectrometer both by free space or via fiber.

You also have several options for reading out over a standard interface like USB or SPI with our different electronics options, which you can see here.

How to assemble the PEBBLE Evaluation Kit

Which spectrometer to use?

Do you need to evaluate a spectrometer for your next project?
We understand that it can be hard to judge the performance of a spectrometer just from the data sheet. Therefore, we offer a time limited loan of a demo unit to customers that meet certain criteria.
