SST08 Lightweight Time-Correlated Single-Photon Counting System

The SST08 is Saluki’s latest lightweight time-correlated single-photon counting system. Integrating the latest time measurement chip technology, the SST08 boasts a time resolution as low as 4 ps, an RMS jitter of only 25 ps, and a dead time of only 4 ns, supporting instantaneous saturation count rates up to 250 Mcps.

The SST08 offers nine channels, including one synchronization channel and eight counting channels. The Saluki SST08 utilizes a new lightweight design, significantly enhancing deployment flexibility and convenience. This frees photon measurement from space constraints and allows it to be deployed in a variety of environments, demonstrating exceptional adaptability in complex environments and within compact system integration requirements.
