Detectors for Spectroscopy

HORIBA provides single-channel detectors (SCDs) or multichannel detectors (MCDs). The Single-channel detectors have one active sensing element that acts as single transducer. Photons reaching the detector, within its operating wavelength range, are absorbed by the active material of the detector and encoded as an electrical signal. The output signals produced vary according to the detector specifications, but generally include analog (voltage or current) and digital (pulse-counting) domains. multichannel detectors have multiple active sensing areas which collect many wavelengths simultaneously at the focal plane of a spectrograph. Each arrangement has advantages and disadvantages, and it is the application requirement that defines which configuration is most suitable.
