The optical axis of a measuring unit can be confirmed by the following methods.

ｂ

 

As shown on the right, the red laser beam is visible on a 

piece of white paper placed on the reception window. 
Adjust it so that the incidence of the laser beam is in the 
center of the reception window. 

The incidence should be in the center horizontally and at 

the position where “a” is equal to “b” vertically. Make 
adjustments to reduce such deviations, as shown in the 
figures below, where (a) is the vertical deviation, (b) is the 
horizontal deviation,(c) is the inclination of the laser beam.

(a): Vertical orientation            (b): Horizontal orientation          (c): Laser beam inclination 

 

  The laser scanning range is defined by the distance between the emission unit and the 

reception unit mounted on the standard support base. If the distance between the 
emission unit and the reception unit is greater than standard, a slight machining error will 
be amplified to the extent it disables the proper reception of the scanning beam. This 
should be considered when designing a dedicated fixture.
