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 ...

First Sensor erweitert sein Angebot an optischen Sensoren um innovative Silizium-Photomultiplier (SiPM). Damit lassen sich auch geringste Lichtmengen messen und sogar einzelne Photonen nachweisen.

Photomultiplier, Photoelektronenvervielfacher, Sekundärelektronenvervielfacher, hochempfindliches Gerät zur Verstärkung kleinster Lichtsignale und zu deren ...

A photomultiplier tube is a device used to measure very low levels of light. It’s a common tool of particle physics when trying to detect just a few photons. It turns out that running a tube at ...

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 ...
