HP-MSM-HB
35,0(6
Check the space available before mounting the device, especially the required space for the connection
cables and the movement range of the z-axis (see chapter 21, „Dimensions“, on page 79). The device
must be set up so that it is stable and fastened with screws (see chapter 7.3 on page 21).
The HP-MSM-HB is designed to operate in a horizontal position with a beam incidence from above.
NOTICE
Damaging/destroying the device
Obstacles in the movement range of the HP-MSM-HB can lead to collisions and damage the
device.
X
Keep the movement range free of obstacles (cutting nozzle, pressure rolls, etc.).

Manually aligning the HP-MSM-HB
7.3.1
Important conditions for the position of the focused laser beam
Due to the imaging characteristics of the measuring objective it is necessary for the laser beam focus to be
positioned in a certain range above the measuring objective.
NOTICE
Damaging/destroying the device
The focus has to be in a defined range with reference to the measuring objective. In case it
is too close or too distant, the optics might be damage in case of high beam intensities.
X
Use the enclosed alignment tool for the alignment.
The size of the range in which the focus is to be positioned before the first measurement depends on the
divergence of the focused laser beam and the power used. The measurement range is between an upper
and a lower limit.
Upper limit
If the focus is located too high above the measuring objective, a focus on the image-sided beam path can
develop. Together with too high beam intensities, the optics might be damaged. In addition, over-illumination
of the aperture may occur, resulting in damage to the aperture.
Measuring plane
The power density distribution of the measuring plane is displayed on the CCD sensor.
Lower limit
If the focus is too close to the measuring objective, the beam splitter may be damaged, depending on the
type of focusing and the power used.
