说明
The SPC-150N is an all-purpose TCSPC and FLIM module with PCI bus interface. The board can be used for fluorescence lifetime measurements, single molecule spectroscopy, FCS and FCCS recording, FLIM, Mosaic FLIM, FLITS, and combined FLIM / PLIM applications.
The SPC-150NX is a resolution-enhanced version of the SPC-150N for ultra-fast detectors. The board can be used for traditional fluorescence lifetime measurements, single molecule spectroscopy, FCS and FCCS recording, FLIM, Mosaic FLIM, FLITS, and combined FLIM / PLIM applications. The SPC-150NX is recommended especially for applications that require ultimate time resolution from superconducting detectors, MCP PMTs, and fast hybrid detectors.
General Information
The SPC-150N boards have a large internal memory and a fast bus interface and ultra-fast discriminators in the detector- and synchronization inputs. This allows the modules to obtain superior time resolution with detectors that both have low transit time spread and an extremely fast single photon response. They are recommended especially for superconducting detectors, MCP PMTs, and fast hybrid detectors with bi-alkali or multi-alkali cathodes. They offer all standard photon distribution modes, the continuous-flow mode, the FIFO (time-tag) mode and the FIFO Imaging (FLIM) mode is implemented. The SPC-150N board can thus be used for traditional fluorescence lifetime experiments, diffuse optical tomography, stopped flow experiments, single molecule spectroscopy, FCS and FCCS recording, FLIM, Mosaic FLIM, FLITS, and combined FLIM / PLIM. One or more SPC-150N modules are used for the bh DCS-120 confocal FLIM system. They are also the basis of standard FLIM systems for the Zeiss LSM 710 and 510 microscopes and various other confocal and multiphoton laser scanning microscopes.
The SPC-150NX board is a resolution-enhanced version of the SPC-150N. The minimum time-channel width is 405 fs. These modules are recommended especially for applications that require ultimate time resolution from superconducting detectors, MCP PMTs, and fast hybrid detectors. The SPC-150NX achieves sub-20 ps (FWHM) IRF width with these detectors.
Measurement Software Included

原则
The bh SPC modules use a multi-dimensional TCSPC principle. The principle is an extension of the classic TCSPC process: A detector detects single photons of a periodic light signal. The TCSPC electronics measures the times of the photons within the signal (excitation) period, and builds up the distribution of the photons over the time of the signal period. The time resolution of the TCSPC process is much higher than the resolution of an analog recording with the same detector: The time of a photon pulse can be determined with a much higher precision than its width.
In extension of the classic process, the bh technique determines additional parameters of the photons, such as wavelength, point of origin within an image area, excitation wavelength, time from an external stimulation of the sample, time within an additional modulation period of the excitation light. The photon distribution is built up over the photon times in the signal period and one or several of these additional parameters. The results of this process are multi-wavelength fluorescence-decay data, fluorescence-lifetime images, multi-wavelength lifetime images, multi-excitation decay data or multi-excitation FLIM data, decay data or FLIM data of fast dynamic changes within a sample, or combined fluorescence / phosphorescence decay data or FLIM / PLIM data. Please see also ‘The bh TCSPC Technique’.
