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.

2.The tolerance for and ideal straight line obtained by determining the average height of and OMRON standard measurement object for the beam line.
The CCD high-resolution mode is used. Linearity varies depending on the measurement object.

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 the measurement object.

Note:The image input periods listed here are for fixed/auto sensitivity. The image input period will be longer for multi-sensitivity, high-speed multi-sensitivity, or other settings. When the high-power mode is ON, the shortest image input period is 95 ms regardless of the setting of the CCD mode.
Use the eco monitor in the RUN mode to determine the actual image input period.
