Measurement through a window
In the case of measurement through a window, various different light reflections may occur.
On the one hand due to direct incidence on the window (e.g. due to contamination or
scratches), on the other hand due to reflections at the window (that is due to objects behind
or beside the LMS1xx). Reflections of objects on the window must be shaded.
