Note: 1 . Obtained by setting an OMRON standard measurement object at the
measurement center distance and determining the average height of
the beam line. The conditions are given in the table below. However,
satisfactory resolution cannot e attained in strong electromagnetic
fields. The minimum resolution of the ZG2-WDS8T/WDS3VT is
0.25 µm, even when the average number of operations is increased.
Resolution does not go any lower.

3 . A value attained by using an aluminum jig to secure the distance between the Sensor Head and the measurement object. The CCD standard mode is used.
4 . Defined as 1/e2 (13.5%) of the center light intensity. This may be influenced when light leakage also exists outside the defined area and the
reflectivity of the light around the measurement object is higher than
that of measurement object.
