*1.
2
Defined as 1/e
(13.5 %) of the center optical intensity at the actual measurement center distance (effective 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 in the measured value with respect to an ideal straight line. The standard workpiece is white aluminum ceramics in diffuse reflection mode and
glass in the regular reflection mode of the ZS-LD20T/40T/50. Linearity may change according to the workpiece.
*3.
This is the peak-to-peak displacement conversion value in the displacement output at the measuring center distance in high-precision mode 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 aluminum ceramics in diffuse re-
flection mode and glass in the regular reflection mode.
*4.
This is the value obtained at the measuring center distance when the Sensor and workpiece are fixed by an aluminum jig.
*5.
This value is obtained when the measuring mode is set to the high-speed mode.
