The SPC-QC-104 offers the usual modes for recording temporal waveforms of optical signals, sequential recording multi-wavelength recording, time- and parameter-tag recording, FLIM, spatial and temporal mosaic FLIM, triggered accumulation of fast time series of curves and images, and simultaneous FLIM / PLIM.
Unlike the SPC-130 and -180 TCSPC modules, which use a TAC/ADC principle, the SPC-QC uses direct time-to-digital (TDC) conversion.
The TAC-ADC principle uses a linear voltage ramp between a start pulse (usually the photon) and a stop pulse (usually a reference pulse from the laser).
The voltage is converted in a digital data word which expresses the time of the photon in the laser pulse sequence.
In the TDC principle, the photon pulses from the detector(s) and the reference pulses from the laser are sent through chains of delay elements. The timing logic looks at the data in the delay chains, and identifies start-stop pairs of photons and laser pulses, determining the temporal positions of the photons in the laser pulse sequence.
From this data, the usual TCSPC / FLIM photon distributions are built up.
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, FCCS) acquired in multiple operation modes. SPCM software undergoes active continuous development. SPCM receives frequent updates with new features.
For advanced fluorescence lifetime imaging (FLIM) and single-curve data analysis, please use SPCImage.
For advanced fluorescence correlation spectroscopy (FCS) and cross-correlation (FCCS) data analysis, please use Burst Analyzer.
For automation and custom software integration, DLLs and LabVIEW drivers are available.
