Timing & signal acquisition
DCS900PC Time-Correlated Photon Counting
A time-correlated single-photon counting acquisition unit covers fluorescence decay, phosphorescence and afterglow measurements with selectable time bins and a wide acquisition window.
Best suited to
Lifetime measurements from repeated weak emission signals.
Selecting a configuration
Specify the detector pulse output, excitation reference and expected count rate. Choose a window that captures the full decay, then select the bin size; the minimum bin is not the complete instrument response.
Measurement & configuration
- Up to 65,535 acquisition channels.
- Steady-state acquisition support.
- USB 3.0 data connection.
