Collectors charge-coupled device

The latest designs in area detectors employ charge-coupled devices (CCDs) as detectors. In effect, CCDs are photon counters, solid-state devices that accumulate charge in direct proportion to the amount of light that strikes them. They have found use in astronomy as light collectors of great sensitivity. For... 

Silver nanoparticles were also used to improve the detection of liquid solutions of analytes at a target-collector distance of 7 m. The experimental setup of the prototype instrument used to perform standoff Raman detection is schematically shown in Figure 8. The prototype system consists of an Andor Technologies Shamrock spectrograph equipped with a charge-coupled device detector (CCD), a reflecting telescope, a fiber optic bundle cable, a notch (or edge) filter assembly and a laser source (532 and 488 nm) for active standoff Raman detection.
