OFG / PLG Optical fibers and fiber plug adapters
In order to connect the measurement head or optical probes to the spectrometer, Instrument Systems supplies a range of optical fiber guides (OFG-xxx). These are not attached directly to the spectrometer, but instead to a fiber plug adapter (PLG-xxx) appropriate for each fiber type. The fiber plug adapter is then mounted on the spectrometer’s entrance port. This innovative concept means that calibration of the spectrometer remains intact when changing the accessories attached.
Properties of the different fiber guides:
|multimode fiber with SMA connector||multimode fiber with core diameter 200 - 1000 µm||superior light transmission for small beam diameters||collecting and transmitting collimated light|
|fiber bundle with ferrule||bundle of fibers each with core diameter of 50 µm||large cross sections possible; bending the fiber does not affect transmission||collecting and transmitting diffuse light|

Instrument Systems supplies appropriate connector adapters for both multimode fibers and fiber bundles. Fiber plug adapters are also available for all popular connectors as used in optical telecommunications and fiber sensor applications.
The fiber plug adapter slides into the optical input of the spectrometer and is fixed with the knurled ring. An alignment pin guarantees accurate and reproducible installation. Furthermore, the fiber plug adapter ensures efficient coupling of the light into the spectrometer due to the integrated lens that matches the fiber NA (numerical aperture) to the f-number of the spectrometer.
