Description
General Information
The SPC-QC-004 TCSPC module has three parallel TCSPC channels with a common reference channel on a single PCI-express board. Alternatively, the module can be operated with four absolute photon timing channels. The module features high temporal and spatial resolution, high peak count rate, and extraordinarily high timing stability. The SPC-QC-004 offers the usual modes for recording temporal waveforms of optical signals, sequential recording multi-wavelength recording, time- and parameter-tag recording, triggered accumulation of fast time series of curves and simultaneous fluorescence and phosphorecence decay recording.
Measurement Software Included
The SPCM operating and measurement software is included with all SPC series modules. SPCM provides online calculation and display (2D, 3D) of data (decay curves, FCS and FCCS) acquired in multiple operation modes. SPCM software undergoes active continuous development. SPCM receives frequent updates with new features and bug fixes. Read more…
