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 ... “For example, we’re now developing hyper-output laser sources that are emerging as a critical technology for fusion ...

The device includes a voltage reference generator to initiate the chemical reaction and a photomultiplier tube (PMT ... expansion board and the live output can be viewed in ppLOGGER in real ...

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.

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 ...
