Ibsen Photonics launches PEBBLE NIR – Ultra Compact Spectrometer Modules for Instrument Integrators

Our clusterpartner Ibsen Photonics, the global leader in fused silica transmission gratings and industrial grade spectrometer modules, today announced the ultra compact PEBBLE NIR OEM spectrometer.

Ibsen’s PEBBLE NIR spectrometer is an addition to the PEBBLE platform of ultra compact spectrometers with a form factor of only 23 mm x 21 mm x 8 mm, high resolution, and sensitivity, as well as environmental ruggedness. 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.

With PEBBLE NIR, we are addressing the market demand for cost efficient yet high performance spectral sensors with excellent transferability”, says Thomas Rasmussen, Director of Product Management.

The core of PEBBLE is a highly effective transmission grating manufactured in-house at Ibsen. Furthermore, PEBBLE utilizes a compact and very sensitive InGaAs detector array with short integration time. When combined with a large numerical aperture of 0.22 (low f-number of f/2.2) PEBBLE provides high sensitivity and fast speed for such a small spectrometer.

A key benefit of using a transmission grating inside PEBBLE is a high resolution of 12 nm across the full 950 – 1700 nm wavelength range. Furthermore, the pure transmission-based optics inside PEBBLE ensures a very good thermal stability, and make it ideal for real time measurements in the field.

PEBBLE NIR offers a cost-effective and low-risk solution for integrators of handheld and portable multi-spectral instruments for biophotonics, medical, food, and precision agriculture applications based on fluorescence or absorbance measurements.
