● Angle between the measurement center and the sensor head
Diffuse reflection surface
Mount the sensor head as shown at the right, so
the emitter surface and receiver surface of
sensor head is parallel to a measuring target.
For the measurement center distance and
measurement range, refer to “8-2 Sensor
Head Specifications” .
Specular reflection surface
Mount the sensor head as shown at the right, so
the angle between the emitting and receiving
laser light is symmetry to a measuring target.
Make sure that the specular reflection line (tilt
of the head) is perpendicular to a measuring
target as shown in the right.
For the measurement center distance and
measurement range, refer to “8-2 Sensor
Head Specifications” .
■ Mounting ND Filter
Mount the ND filter (option) in case the amount of reflected beam is too large on
specular reflection installation.
Securely tighten the two attached M2.6 bind screws (4mm length) to two screw holes
on the sensor head. The tightening torque should be 0.3N·m or less.
Carefully mount ND filter not to get fingerprints or damage on the glass. If
you do get fingerprints or other stain on the lens, wipe it off with an optical
cloth.
