For measuring conditions, refer to "8-2 Sensor Head Specifications" - "CHECK in specifications".
*1 The measurement range is between +0.1 and +1.0mm (in case the sampling cycle is 20μs), or
between +0.8 and +1.0mm (in case the sampling cycle is 10μs).
*2 The figure shows the value at measurement center distance. It is determined by 1/e
（ approximately 13.5% ） of center beam intensity. The reflectance around the detecting point
may be higher than at the point due to leak light outside the specified area, and this may affect
the measurement value.
*3 The minimum resolution of 0.25μm can be achieved if the sensor head is connected to the
controller that is not subject to "Foreign Exchange and Foreign Trade Law".
*4 The linearity of ±0.025%F.S. can be achieved if the sensor head is connected to the controller
that is not subject to "Foreign Exchange and Foreign Trade Law".
*5 Variance is ±0.02 ％ F.S. or less depending on the ambient illuminance.
