PEBBLE Ultra Compact OEM Spectrometers

Ultra Compact and high performance

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

  • Tiny footprint
  • High optical resolution
  • High throughput
  • Low stray light
  • Robust, athermal design

PEBBLE combines an ultra compact form factor with high resolution and sensitivity as well as environmental ruggedness and is the ideal OEM solution for all those handheld and portable system applications, where performance cannot be sacrificed to obtain compactness and/or low cost


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

  • Healthcare and lifescience
  • Food and agriculture
  • Light measurement
  • Semiconductor manufacturing
  • Security
  • Biophotonics and pharmaceuticals

On our application pages you can find help to identify which of our spectrometer platforms best suits your needs.

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 variation. 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.
