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 ...

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 ...

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 ...

A photomultiplier tube is a device used to measure very low ... The difference being that the components inside the glass dome make up the detector instead of an amplifier or filament display.

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, ...

The V-650 is a double-beam spectrophotometer with a photomultiplier tube (PMT) detector. The high sensitivity of the PMT enables accurate measurements of low (and high) concentration samples.
