The Tablet Probe was specifically designed to minimize or eliminate the occurrence of random scatter effects traditionally solved in laboratory instrumentation using an integrating sphere. The novel optical design of the Tablet Probe provides MicroNIR users with an easy sample measurement interface without strict and specialized control of the sample and spectrometer. Use of the Tablet Probe with the MicroNIR OnSite allows laboratory and field users to achieve repeatable, reliable and accurate results in difficult, uncontrolled environments.
