Detectors

Edinburgh instruments offer a range of detector modules that are suitable for either single photon counting applications or analogue detection.

Single photon counting detector modules comprise a single photon counting photomultiplier, together with an optimised dynode chain, mounted in a light tight cooled or un-cooled housing. The detector modules include the coupling flange with the adaptive optics for direct compatibility to our range of FLS920, OB920, LifeSpec and mini-tau spectrometers. Special adapters can be offered to couple to alternative systems.

Analogue detectors are used either for high light level applications with the requirement for high dynamic range or as alternative detectors in spectral ranges where photomultipliers are unavailable or too expensive. Depending on the required application, the analogue detectors come in a variety of housings with a variety of cooling options. Analogue detector modules have individual bias requirements and include different amplifiers. They come with a mounting/imaging flange attached. Analogue detectors find application in the LP920 laser flash photolysis spectrometers to extend the spectral coverage into the NIR to 2.5µm or beyond.

Edinburgh instruments have integrated many customer specific detectors into their spectrometer range. Ask the sales department or distributor for special detectors.
