ATR Loop InfraRed Fiber Optic Probes

ATR Loop InfraRed Fiber Optic Probes

ATR Loop Infrared PIR-fiber probes are designed for use with FTIR and other Mid IR spectrometers. ATR Loop PIR-fiber probes are ideal for remote analysis of the composition of liquids, pastes and soft surfaces with no need in sample preparation.
ATR Loop Infrared PIR-fiber probes enable low-cost ATR-spectroscopy.
