Every spare linescanner window is supplied with the correct transmission factor for the spectral response of the linescanner it is supplied for.
Note - all windows for linescanners are the same material (Mica). As a workaround you could leave the transmission factor unchanged.
The transmission factor supplied is to ensure measurement errors (after changing) are kept to a minimum
Procedure - please note in this example the greyed out text - this is only due to not having a scanner connected at the time of taking the screenshot. With a scanner connected - you will see this text as black
Step 1 - In the running software - choose Transmissivity of the scanner's window from the Scanner dropdown tab.
