Environmental Factors

It is necessary that environmental factors are properly set to achieve optimal radiometric accuracy. In the Web Setting App, they are available in the Radiometry Tab. The parameters are described as follows:

• Window Temperature: The temperature of the IR transmissive window in the optical path of the camera • Window Transmission: The transmission of the IR transmissive window • Window Reflection: The reflection of the IR transmissive window. • Window Reflection Temperature: The reflection of the internal temperature on the camera side of the window off the IR transmissive window. • Atmospheric Transmission: Transmission of the atmosphere in the optical path between the camera and the target • Atmospheric Temperature: Temperature of the Air between the camera and the target • Emissivity Target: Emissivity of the target being measured • Background Temperature: Temperature of the scene background being imaged. Generally, this will be near ambient.
