Transmission <options>
Changes the transmission percentage of the infrared-
transparent window (IR window).
When you do infrared inspections through IR windows, not
all of the infrared energy emitted from the target is
transmitted through the optical material in the window. If
you know the transmission percentage of the window,
adjust the transmission percentage in the Imager or in
SmartView software to improve the accuracy of the
measurement.
Note
If Display is set to Display All, the
transmission correction shows as t = xxx% on
the display.
