FLIM升级模块--配合Leica TCS SP8 共焦显微镜
Leica TCS SP8, FCS and FLIM
The Leica TCS SP8 confocal microscope series can be easily upgraded to Fluorescence Lifetime Imaging (FLIM) and Fluorescence Correlation Spectroscopy (FCS) capability using photon counting detection. Data are acquired using one of two modalities:
- the FastFLIM (digital frequency domain); or
- the TCSPC (time-domain).
FastFLIM (proprietary technology) is the new digital frequency domain (DFD) approach to FLIM measurements. Its advantages, when compared to the TCSPC are twofold:
a) the short time required for data acquisition; and
b) the higher sensitivity of the technique (due to the 100% duty-cycle).
Alternatively, FLIM data can be acquired using the TCSPC method, or both methodologies can be implemented on the same instrument.
The Leica, FCS and FLIM upgrade package includes the following items:
|FastFLIM Unit or TCSPC Unit||It accepts the output (via BNC) from up to four PMTs of the confocal unit. The synchronization signal from the Leica confocal head is connected to the unit.|
|Detectors||Leica HyD detectors|
|Laser Launcher||Super-continuum (white light) laser as well as range of individual laser line options.|
|Computer Running VistaVision by ISS||A separate computer, with a 27" flat monitor|
