Stanford SR400 Photon Counter

Stanford Research Systems

The SR400 Dual-Channel Gated Photon Counter from Stanford Research System offers a convenient, integrated approach to photon counting that avoids the complexity and expense of old counting systems. No longer is it necessary to mix and match amplifiers, discriminators, gate generators and counters. The SR400 combines all these modules into a single, integrated, microprocessor controller instrument. Complete measurement tasks such as background subtraction, synchronous detection, source compensation and pile-up correction can all be performed easily with the SR400.

Features:

  • Two independent counting channels
  • Count rates to 200MHz
  • 5ns pulse-pair resolution
  • Gated and continuous modes
  • Gate scanning for time-resolved counting
  • Built-in discriminators
  • Gate and discriminator outputs
  • GPIB and RS232 interfaces

The SR400 has two independent channels that can count rates up to 200MHz. Different counting modes allow you to count for a fixed amount of time, until a certain number of counts have been received or for a fixed number of triggers. Each counting channel has its own date generator providing counting gates as short as 5ns or as long as 1s. The gates can be set in a fixed position relative to the trigger signal, or scanned to measure lifetimes or recover time-varying waveforms.
