Light Reflectance Probe

In order to correct fluctuations and drift from your light source, periodic referencing is required. To facilitate this, Avantes offers this series of reflection probes with a self-referencing feature.

The light coming from the light source is bundled into 12 fibres, which are split into two 6-fibre bundles. One of these bundles is carried to the probe end for sample measurement and the other bundle of 6 are directed to a white reflection tile built into the probe to provide a light source reference. This reference leg is connected to a slave spectrometer channel dedicated to light source referencing or may be routed to a single channel via a fibre-optic (contact a Sales Engineer about this special configuration). On the measurement side, the probe end has a seventh fibre, which reflects light back to the master spectrometer channel.

Technical Data
