Ibsen Photonics Launches PEBBLE VIS-NIR – Ultra Compact Spectrometer Modules for Instrument Integrators

For immediate release

Press Release – Farum, February 23, 2021

Ibsen Photonics (ibsen.com), the global leader in fused silica transmission gratings and industrial grade spectrometer modules, today announced the ultra compact PEBBLE VIS-NIR OEM spectrometer.

Ibsen’s PEBBLE VIS-NIR spectrometer is an addition to the PEBBLE platform of ultra compact spectrometers with a form factor of only 20 mm x 15 mm x 8 mm, high resolution and sensitivity, as well as environmental ruggedness. PEBBLE VIS-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 variation.

”I found that the PEBBLE was more compact and better performing than other compact spectrometers”, says Kristian Nielsen, CTO of SHUTE Sensing Solutions. “The PEBBLE has better sensitivity, higher resolution, and smaller packaging than similar spectrometers.”

The core of PEBBLE is a highly effective transmission grating manufactured in-house at Ibsen. Furthermore, PEBBLE utilizes a fast and very sensitive CMOS detector array with 256 pixels. When combined with a large numerical aperture of 0.22 (low f-number of f/2.2) PEBBLE provides amazingly high sensitivity for such a small spectrometer.

A key benefit of using a transmission grating inside PEBBLE is a high resolution of 8 nm across the full 500 – 1100 nm wavelength range. Furthermore, the pure transmission-based optics inside PEBBLE ensures very good thermal stability and makes it ideal for real-time measurements in the field.

PEBBLE VIS-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.
