Explanation
Term or expression
The areas that contain temperatures outside the
present level/span settings are colored with the
saturation colors. The saturation colors contain an
‘overflow’ color and an ‘underflow’ color.
There is also a third red saturation color that marks
everything saturated by the detector indicating that
the range should probably be changed.
saturation color
The interval of the temperature scale, usually ex-
pressed as a signal value.
span
Amount of energy emitted from an object per unit
of time, area and wavelength (W/m
2
/μm)
spectral (radiant) emittance
The current overall temperature measurement
limitation of an IR camera. Cameras can have
several ranges. Expressed as two blackbody tem-
peratures that limit the current calibration.
temperature range
The way in which an IR image currently is dis-
played. Expressed as two temperature values lim-
iting the colors.
temperature scale
infrared image
thermogram
Gases and materials can be more or less transpar-
ent. Transmission is the amount of IR radiation
passing through them. A number between 0 and
1.
transmission (or transmittance) (factor)
An isotherm showing a linear spread of colors, in-
stead of covering the highlighted parts of the im-
age.
