Reflected light intensity
During the measurement, light can be reflected from several surfaces at the same
time; for example, from the front and rear of a transparent measuring object.
Direction of detection: The device assigns numbers to the scanned surfaces. This
means that the measurement can focus on individual reflection points (peaks). The
numbers are assigned (using the direction of detection: near/far) in such a way that
they either increase (near) or decrease (far) beginning on the side closest to the sensor.
Example based on four glass panes:
1 (8)*
2 (7)
3 (6)
4 (5)
7 (2)
8 (1)

1 = Near
(8) = Far
Near is selected as the standard setting, i.e., the numbering increases from the side
closest to the sensor.
