Can be used to detect single photons.
It uses the photoelectric effect multiple times to produce a chain reaction. In particular, as mentioned at youtu.be/5V8VCFkAd0A?t=74 from Video 1. "Using a Photomultiplier to Detect single photons by Huygens Optics" this means that the device has a lowest sensitive light frequency, beyond which photons don't have enough energy to eject any electrons.

. Source. 2024. Wow this dude is amazing as usual. Unfortunately he's not using a single photon source, just an LED.
A photomultiplier tube (PMT) is a highly sensitive electronic device that detects and amplifies light. It is commonly used in various applications, including particle physics, medical imaging, nuclear and radiation detection, and fluorescence spectroscopy. The PMT operates by converting incoming photons into an electrical signal, which can then be measured.
