The DPC-230 is a photon correlator module that records absolute photon times in up to 16 parallel detection channels. The board can be used for traditional fluorescence lifetime measurements, single molecule spectroscopy, FCS and FCCS recording, FLIM. The board offers a PCI interface and can be easily installed in nearly all PCs.

General Information

The DPC-230 especially targets at a new type of fluorescence correlation spectroscopy that records correlation over a time range of 10 orders of magnitude. Thus, singlet decay rates, rotational relaxation rates, rate constants of conformational changes, triplet transition and decay rates, and diffusion times of free fluorophores and fluorophores bound to proteins, lipids or nanoparticles can be obtained within a single measurement. Another application may be diffuse optical correlation experiments which require autocorrelation in a large number of detection channels.
The DPC-230 photon correlator card records absolute photon times in up to 16 parallel detection channels. The time resolution of the recording is 165 ps per time channel. Depending on how the photons are correlated, fluorescence correlation (FCS), fluorescence cross correlation (FCCS), or photon counting histograms are obtained. Moreover, the DPC-230 can be used for recording luminescence decay curves and fluorescence lifetime images from the sub-nanosecond to the millisecond range, for LIDAR experiments, time-of flight mass spectroscopy, or any other experiments based on acquiring the temporal distribution of detection events in a large number of detector channels.

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, FLIM, FCCS) acquired in multiple operation modes. SPCM software undergoes active continuous development. SPCM receives frequent updates with new features and bug fixes. Read more…
