Detector modules, into which the entire drive electronics have been integrated, were developed to facilitate the application of detectors. PIN modules and APD modules are available along with intelligent sensors which are – thanks to their interfaces – ready for application in Industry 4.0.
Symmetrical photodetectors are required to measure differential optical signals in fiber-optic sensor systems and systems for optical coherence tomography (OCT).
Symmetrical InGaAs photodetectors, also referred to as balanced detectors, are used in fiber-optic applications in optical coherence tomography and fiber sensor technology. Mach Zehnder interferometers are also available with integrated symmetrical detectors.
Different models are available as balanced detectors:
