(*1) Defined as 1/e
value). The beam 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 aluminum (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 measuring
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 workpiece is white aluminum ceramics in the diffuse reflection mode and
glass in the regular reflection mode.
(*4) This is the value obtained in the measuring center distance when the sensor and workpiece are fixed by
an aluminum jig (typical example).
(*5) This value is obtained when the measuring mode is set to the high speed mode.
