Reflectance Probe with Reference Optical Path

Name: Reflectance Probe with Reference Optical Path
SKU: OFFP-0007

Cat No:OFFP-0007

Description

To correct for fluctuations and drifts in the light source, regular reference measurements are required. Light from the source is coupled into a 12-fiber bundle, which is then split into two 6-fiber bundles. One bundle is connected to the probe tip for sample measurement, while the other is directed to a white reference tile built into the fiber probe for light source reference. This reference fiber bundle connects to a secondary channel spectrometer dedicated to measuring the light source reference or can be combined with the signal light via a fiber optic adapter to a single-channel spectrometer (contact sales engineers for details on this special configuration). At the measurement end, a seventh fiber in the probe tip returns the reflected light to the main channel spectrometer.
