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:
  • Internal detectors
  • 2-detector unit coupled to the fiber optic port of the microscope
  • 2-detectors coupled to the confocal head of the microscope
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)
