Reflective surfaces
The laser beam is almost completely deflected on reflective surfaces. This means that
an object hit by the deflected beam may be detected instead of the reflective surface.

Small objects
Objects that are smaller than the diameter of the laser beam cannot reflect the laser
light’s full energy. The portion of the light beam that does not reach the object is lost. If
all of the light reflected to the sensor is insufficient, the object may not be detected.
The portion of the light that does not reach the front object can be reflected by a larger
object in the background. If all of the light reflected to the sensor is sufficient, this
object is detected. This can lead to a corruption of the measured value.

Scanning range
The scanning range of the device depends on the remission of the object to be
detected. The better a surface reflects the incident beam back to the device, the
greater the scanning range of the device.
