The device includes a voltage reference generator to initiate the chemical reaction and a photomultiplier tube (PMT ... showed a slightly lower limit of detection than the standard setup.

Conventional photomultiplier tubes capture the faintest light and ... “I’ve always been interested in low-light imaging and detection, and I’ve been working on various devices for almost ...

The laser driver needs to push many amps to get a fast enough rise time, and the only sensor that’s fast enough to not smear the signal is a photomultiplier tube. But persistence pays off ...

A vacuum tube that converts light into electrical energy and amplifies it. Photomultiplier tubes are used in high-end drum scanners, because they are more sensitive to light than the CCD elements ...

In both techniques, sensitive light detectors called photomultiplier tubes are arrayed around the tank to record the intensity of the faint light. The intensity of the scintillation provides ...

The V-660 is a double-beam spectrophotometer utilizing a double monochromator and a photomultiplier tube detector.The use of a double monochromator provides high resolution with extremely low ...

This course dives into nanophotonic light-emitting devices and optical detectors, including metal semiconductors, metal-semiconductor insulators, and pn junctions. We will also cover photoconductors, ...
