ATR-Loop PIR-Fiber Probe

The ATR-Loop Infrared PIR-fiber probe, available from art photonics, is the first device in the FlexiSpec® product range to be developed for use with all Mid IR spectrometers, including FTIR.

The ATR-Loop PIR-fiber probes eliminate the need for sample preparation and are ideal for remote analysis of the composition of soft surfaces, pastes, and liquids. Within the FlexiSpec® product line, the loop fiber probe is the simplest device to facilitate affordable ATR-spectroscopy.
