FLIM升级模块--配合Olympus 共焦显微镜
Olympus, FCS and FLIM Upgrade
The FV1000, FV1200, FV3000 and FVMPE-RS confocal microscopes systems 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).
The Olympus FCS and FLIM Upgrade Kit 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 Olympus confocal head is connected to the unit. |
Detectors |
Options of:
|
Detectors | fast PMTs or SPADs. |
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 |

The upgrade can be carried out following one of two modalities:
a) By adding two external PMTs (2-detector unit); the fluorescence signal is collected through the fiber port of the microscope and diverted to the 2-detector unit (Figure 1)
b) Utilize the internal PMTs of the FV1000 (Figure 2)
