Photon counters

Dual-channel gated photon counters offer a convenient, integrated approach to photon counting that avoids the complexity and expense of older counting systems. It is no longer necessary to mix and match amplifiers, discriminators, gate generators, and counters.

SR400 gated photon counter

The SR400 gated photon counter combines two measurement channels, three 200 MHz counters, programmable discriminators and independent gate generators in one bench instrument. It supports continuous, gated and scanned counting for PMT measurements, lifetime studies, waveform recovery and background-corrected experiments.
