The following measurement conditions are applied unless otherwise specified; power voltage: 24
VDC, ambient temperature: 20°C, sampling cycle: 500 μs, average number of sampling times: 1024
times, measurement center distance, and measurement object: white ceramic.
*
1 The diameter is the size of the object at the measurement center distance and determined by 1/e
2
(approximately 13.5%) of the center beam intensity. The reflectance around the detecting point may be
higher than at the point due to leak light outside the specified area, and this may affect the
measurement value.
*2 Variance is ±0.1% F.S. or less depending on the ambient illuminance.
