(*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 (glass in the case of the regular reflection mode). 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
High-Resolution mode. The workpiece is white alumina ceramics in the diffuse reflection mode and glass in
the regular reflection mode.
(*4) This is the value obtained in the measurement center distance when the sensor and workpiece are fixed by
an aluminum jig. (typical example)
