VTobj / VTamb Characteristics  
The VTobj and the VTamb characteristics of thermopile sensors depends not only on object and ambient  
temperature but on several other factors like object size to spot size relation, ambient temperature com-  
pensation behaviour or optical filter characteristics. Therefore it is not possible to specify a general VTobj  
and VTamb characteristic. Those characteristics will be specified application specific in a separate cus-  
tomer specification.
