11.2 Interactance Immersion Probe
The Interactance Immersion Probe is quite similar
to the Interactance Reflectance Probe. It uses the
same type of fiber bundle with concentric light
paths.
The only difference is the “lens barrel” which
directs the light in a different geometry.
All adjustments and tests (except Window correction) are done with the Interactance reflectance
probe. Dismount the Interactance Immersion probe and install the Interactance reflectance probe.
