InfraTec GmbH
What are the advantages of a Pyroelectric Detector What is the advantage of a Pyroelectric Detector with an Integrated Beam Splitter?. Beam splitter detectors are multi-channel detectors with only a single aperture. The incoming radiation is divided into two or four spectral channels by micro mirrors inside the detector. The 2.5 mm diameter aperture allows the use of very small cuvettes for NDIR gas analysis. This results in a very low dead volume for the measurement system. In addition, many effects negatively influencing the measurement act... (read more)Browse Gas Sensors Datasheets for InfraTec GmbH -
