LabSpion user guide 

Full automatic 

By default does the “Viso Light Inspector” software make 
full automatic measurement, meaning adjusting photo 
spectrometer to the background light environment by 
turning off the light source and measuring the background 
light levels which subsequent is subtracted from 
measurements so that measurements can be done even in 
a lit room. The adjustment of the exposure time of the photo 
spectrometer also known as integration time is also done 
automatically. 

A measurement is simply started by clicking on the 
play icon. 

 

Then is integration time automatically 
set. 

 

Then is the ambient light level 
automatically measured by turning off 
the light source. 

 

The light source is then turned 180 degrees to prepare for 
measurement.  

Power is then measured and stored.
