By using the depletion laser 592nm, the samples can  be bleach very quickly, so first scan the sample in 

standard 

Confocal 

mode to find the focus and prepare the STED configuration close to work. 

 

Set the WLL laser line  that you need to use (

10 to 30 %

). 

 

Select the Hyd 2 detector and set it at 

100%. 

 

Introduce  to the Hyd a bandwidth that is 

10nm fahter  

 

to the WLL line that you set, and maximum 

10nm lower  

 

than the wavelength of the laser depletion ( +/-582nm). 

 

Use a format like 

512x512

 or 

1024x1024

 

Use a scan speed like 

400HRZ 

 

Use a zoom factor from 

4 to 6
