*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 and measurement target are fixed with an aluminum jig. The CCD mode is
the standard mode.
2
*4:
Defined as 1/e
(13.5%) of the central light intensity. Leakage of light is also present in areas other than those
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.
*5:
This is the calculated resolution when measuring the edge position and edge width.
