Beschreibung
Zusammenfassung:A device for detecting elastically scattered radiation comprising: a source (16) of monochromatic radiation having a controllable output, a detector (56 ) for detecting the elastically scattered radiation from a specimen (12), and a signal conditioning circuit (68) comprising a transducer and comparator. The output of the transducer is compared to a threshold signal to produce a control output signal for source (16). The device is further included in a raman spectrometry apparatus that further includes an optical probe (32). Th e probe comprises a fluid-tight body that encloses three optical channels, preferabyl comprising fibers that carry monochromatic radiation to the speciment and separately collect inelastically and elastically scattered radiation from the specimen.
