Measuring frequency

 

in dependence

 

of the field of view

 

 
Measuring frequency in dependence of Offset 

The larger the offset is set, the higher the measuring frequency of the sensor. 

 

 

Measurement conditions

: Background white; Measuring distance 250 mm 

 

 

 
Measuring frequency in dependence of measuring range (width) 

The smaller the range (the width of the measuring field), the higher is the measuring frequency of the sensor. 

 

 

Measurement conditions

: Background white; Measuring distance 250 mm; Offset 0 mm
