FLIM升级模块--配合Nikon 共焦显微镜
Nikon, FCS and FLIM
The Nikon A1 and C2 confocal microscopes 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 Nikon, 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 Nikon confocal head is connected to the unit. |
Detectors | 2-detectors coupled to the descanned port confocal head of the LSM microscope; or to the non-descanned port (for multiphoton instruments) |
Detectors | fast PMTs |
Laser Launcher | Available for 3-, 4- and 6-lasers. The lasers beams are superimposed and the output of the laser launcher is connected to the microscope by using a fiber optic. |
Computer Running VistaVision by ISS | A separate computer, with a 27" flat monitor |
