The measurement on reflective film is based on a vertical angle of incidence on a
40 mm-wide reflective strip and an angular resolution of 0.071°.
The measurement on a white (90 % reflectivity), natural surface is based on a
vertical angle of incidence and an emitted beam that hits the entire surface of the
measurement object.
If the emitted beam is at an entrance angle of 60° ... 70° on the reflective film, the
measured value drops by approximately 50 % compared to the value for a vertical
entrance angle.

Term Explanation
Accuracy The degree to which the measurement
result corresponds to the true value of the
measurement. The accuracy is a relative
error based on a measurement standard.
For practical applications, a distinction is
made between different influencing
factors.
Absolute accuracy The total of all systematic measurement
errors (e.g., linearity, device offset) over a
defined distance range, reflectivity range,
and temperature range that cannot be
eliminated by other actions such as
average determination.
