(*1) Defined as 1/e
diameter is sometimes influenced by the ambient conditions of the workpiece such as leaked light from the
main beam.
(*2) This is the error on the measured value with respect to an ideal straight line. The standard workpiece is
white alumina ceramic. Linearity may change according to the workpiece.
(*3) This is the "peak-to-peak" displacement conversion value of the displacement output in the measurement
center distance when the number of samples to average is set to 128, and the measuring mode is set to the
High-Resolution mode. The standard workpiece is white alumina ceramic.
(*4) This is the value obtained in the measurement center distance when the sensor and workpiece are fixed by
an aluminum jig. (typical example)
