Ibsen - Model PEBBLE VIS-NIR -OEM Spectrometer

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.

This type of diode array spectrometer provides many benefits when used for absorption or fluorescence spectroscopy compared to optical-based filter instruments. In particular, the fluorescence spectrometer is less bulky and more inexpensive than the combination of several emission filters. The compact spectrometer is also easier to use and provides the full spectrum.

The miniature PEBBLE VIS-NIR spectrometer covers a wavelength range of 500 – 1100 nm and offers a resolution of 8 nm. It utilizes a fast S14739 CMOS 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.

• 500 nm to 1100 nm wavelength range
• Numerical aperture of 0.22
• Resolution: 8 nm (typical)
• Fast and very sensitive CMOS detector array with 256 pixels
• Electronics interface: small flex-connector
• Optional SMA fiber adapter and order sorting filter
• Compact footprint of 20 mm x 15 mm x 8 mm – ideal for handheld devices

Product: PBT-105
Wavelength range: 500-1100 nm
Detector: Hamamatsu S14739
Benefit: Cost effective, high sensitivity

How to couple into your spectrometer

You can couple into your spectrometer both by free space or via fiber.

You also have several options for reading out over a standard interface like USB or SPI with our different electronics options, which you can see here.
