F(L)CS Data Acquisition

Figure 178: 

Loading and saving FCS-specific instrument parameter settings

18.4

Measurements Step – FCS Measurement Time Series at 
Multiple Points 

After optimizing the FCS measurement conditions, it is possible to have FCS measurements 
run automatically at previously defined measuring points with the previously defined 
settings. To do so, go to the 

Measurements

 step.

18.4.1

FCS Network Connection

The LAS AF and SymPhoTime programs are synchronized via a network connection. Each 
FCS measurement started in LAS AF in the 

Measurements

 step of the FCS Wizard generates 

a new data file in SymPhoTime. In addition to the synchronization, the network also enables 
transmission of relevant information such as the file name, instrument parameter settings 
(IPS), or comments entered by the user in LAS AF.

During the FCS measurement, an online correlation curve is displayed that is automatically 
saved along with the raw data in SymPhoTime. After the data acquisition, a more detailed 
data analysis can then be carried out offline. 

Do not change Acquisition mode any more

Do not make any more changes to the 

Acquisition mode

 used to acquire 

the last image.

Observe the SymPhoTime manual

For more detailed information about data analysis, refer to the 
SymPhoTime manual.
