FLIM Data Acquisition

5. If you want to view an online lifetime histogram, close the fast FLIM image in

SymPhoTime. Click the symbol

Show Oscilloscope...

and select the

TCSPC histogram

tab.

6. To cancel specimen illumination, select the

Stop FLIM Test

button in the LAS AF

software. This will also stop the online FLIM display in SymPhoTime.

The instrument parameters set for the FLIM measurements (laser lines and associated
intensity, pinhole, scan mode, image size etc.) are kept as separate FLIM settings that are
independent from the image acquisition setting defined in the

Setup Imaging

step. The FLIM

settings defined in the

Setup FLIM

step are automatically transferred to the

Measurements

step.

16.2.9

Count Rate Monitor

The count rate of each channel is displayed in the

Setup

tab. For FLIM, the count rate should

be between 10,000 and 1,000,000 cps (counts per second).

Figure 135:

Count rate monitor in the FLIM Wizard

In addition, the count rate monitor shows the number of photons in the brightest pixel of the
image. This value allows you to evaluate the image quality. The higher the number of
fluorescence photons (counts) per pixel, the more accurately the lifetime can be
determined. This value is updated regularly whenever a new scanning operation starts in
the

Setup FLIM

step of the FLIM Wizard.

16.2.10

Loading and Saving FLIM-specific Instrument Parameter Settings

The instrument parameter setting (IPS) for FLIM can be saved and loaded in the same way
as IPSs for normal intensity imaging.

Save the FLIM settings in the

Setup FLIM

step and settings for intensity image acquisition in

the

Setup Imaging

step.
