Additional Error due to Reflective Background
An additional measurement error may need to be added due to reflective backgrounds. See Specifications of
additional Errors by Background.
Conditions of Background Influence
The OS32C's measurement precision can be affected by the background reflection of an object.
(1) High-reflective background material or object is present in the scanning plane and within 1.2m
beyond the safety zone.
(e.g. acryl panel, stainless steel, reflective tape, mirror)
(2) Low-reflective background material or object is present in the scanning plane and within 1.2m
beyond the safety zone.
(e.g. paint-finished equipment)
If any of the conditions listed above apply to your application, an additional error factor (Z
2) should be
added to the calculated safety zone size.
M = Result of safety zone calculation from safety distance
Z = Additional safety factors (maximum measurement error), Z = Z
1+ Z2
Z1 = The OS32C’s maximum measurement error (100mm)
Z
2 = Additional Error by Reflective Background
