产品描述

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

Please contact us for details on required system configuration.

Acquisition and Analysis Software	VistaVision by ISS
Fluorescence Fluctuations Spectroscopy (FFS) Measurements	Fluorescence Correlation Spectroscopy (auto- and cross-correlation) Photon Counting Histogram (PCH) FFS measurements at target XYZ locations in an image FLCS, Fluorescence Lifetime Correlation Spectroscopy Number & Brightness (N&B)
Imaging Module Measurements	Single-point (intensity, polarization, lifetime) Single plan and z-stack (polarization images, Ratiometric, FLIM)
FLIM images (digital frequency-domain) (single plane and z-stack)	Acquired in digital frequency-domain (DFD). The routine acquires simultaneously a FLIM image and a steady-state image.
FLIM images time-domain (single plane and z-stack)	Acquired in time-correlated single photon counting (TCSPC)
Single Molecule Module	Burst Analysis FRET and Correlation Methods PIE-FRET Methods
Light Sources	Laser diodes: 370, 405, 440, 473, 488, 635 nm Single-photon pulsed lasers Multi-photon lasers Supercontinuum laser
Laser Launcher	Super-continuum (white light) laser as well as range of individual laser line options.
Input Channels	Two (up to four)
Detectors	Leica HyD detectors
CLK	Pixel, Line, Frame
FLIM Image Data Acquisition Minimum Dwell Time	6 µs/pixel
Unit Control	USB
Computer	3 GHz, 8GB RAM, 27" monitor Windows 10, 64-bit
