Specifications
*1 Capacity value when Omron standard mirror surface target is measured at the measurement center
distance as the average of 4,096 times
*2 Material setting for the Omron standard mirror surface target: Error from an
ideal straight line when measuring on mirror surface
The reference values for linearity when targets to measure other than the above
are as in the table below.
*3 Capacity value defined by 1/e2 (13.5 %) of the center optical intensity in the measured area
*4 Temperature characteristic at the measurement center distance when fastened with an aluminum jig
between the Sensor Head and the target and the Sensor Head and the controller are set in the same
temperature environment
