*2: This is the error in relationship to an ideal straight line when an OMRON-standard measurement object was
measured to calculate the average height of all lines.The CCD mode is the standard mode. Linearity
sometimes changes according to the measurement target.

*3: Value obtained when the Sensor Head and measurement target are fixed with an aluminum jig.The CCD mode
is the standard mode.
*4: Defined as 1/e
defined. So, the beam diameter is sometimes influenced where the reflectance of the area surrounding the
measurement target is higher than that of the measurement target itself.
