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 9.5 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.

Developer’s Kit

The PEBBLE NIR is offered with a Mini-DISB Developer’s Kit for a plug and play experience.

The Mini-DISB Developer’s Kit allows you to easily demonstrate the performance of the spectrometer without the need for complex hardware integration or time-consuming programming.

Benefits of transmission grating based spectrometers

The PEBBLE is a series of ultra-compact spectrometers. This is obtained by a unique lens-grating-lens design utilizing Ibsen Photonics’ high dispersion transmission gratings. Furthermore, the spectrometers provide high efficiency and ulra-compact size.

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.
