*1. Indicates the distance from the front of the sensor head. For the pen-type right angle model, there may be an individual variation of up to ±0.15 mm in the distance from the front of the sensor head.
*2. The measurement range applies when the measurement cycle is 100 µs or longer.
*3. Actual value when measuring Omron's standard mirror target at the center measurement distance with an average of 16,384 times.
When connected to an export control trade regulation compliant sensor controller (Model ZW-8000T), the minimum resolution is 0.25 µm regardless of the sensor head or setting conditions.
*4. Error relative to the ideal straight line when measuring Omron's standard mirror target with material setting: mirror
*5. Actual value defined as 1/e² (13.5%) of the peak light intensity at the measurement wavelength
*6. When a fiber extension cable of 2 m or longer is connected, the setting range for the measurement period (exposure time) will change.
For details, please refer to "Setting the Measurement Cycle" in the ZW-8000/7000/5000 User's Manual (SCEA-702).
*7. Actual value of the amount of change in the measured value at the measurement center distance when the space between the sensor head and the target is fixed with an aluminum jig, and the sensor head and sensor controller are installed in the same temperature environment.
Values in parentheses are actual values when using an SUS304 jig.
For thickness measurements, the value is calculated from the difference in height between the front and back surfaces, so it is not affected by temperature changes.
