PEBBLE Spectrometers

Ultra compact and high performance

The PEBBLE platform is a series of cost-efficient, pre-configured ultra-compact OEM spectrometers for VIS and NIR that provide:

  • Full spectrum

  • Tiny footprint

  • High optical resolution

  • High throughput

  • Low stray light

  • Robust, athermal design

The ultra-compact PEBBLE spectrometers come in a VIS, VIS-NIR, and a NIR version. They combine small size with high resolution and sensitivity as well as environmental ruggedness and are the ideal OEM solution for all those handheld and portable system applications, where performance cannot be sacrificed to obtain compactness and/or low cost.

Using a diode array spectrometer for fluorescence spectroscopy can provide many benefits over optical filter-based instruments. If you use more than a few emission filters a diode array spectrometer can be less bulky, less expensive, and easier to use. Furthermore, by obtaining the full spectrum you get the possibility to deconvolute overlapping spectra and perform background and Raman subtraction. The latest CMOS diode arrays are even fast enough that you can perform flow cytometry measurements.



Our spectrometers are well suited as the spectral engine in your analytical instrument for a wealth of applications in:

  • Healthcare and life science

  • Food and agriculture

  • Light measurements

  • Semiconductor manufacturing

  • Security

  • Biophotonics and pharmaceuticals

Fluorometer with PEBBLE

Proven diffraction grating technology

PEBBLE 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. A key benefit of using a transmission grating inside PEBBLE is a high resolution across the full wavelength range. This resolution is one of the best for this size of spectrometer on the market. Furthermore, the pure transmission-based optics inside PEBBLE ensures very good thermal stability.

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.
