The following steps are used to check that the laser beam is input into the linear translator
module and output from the module centrally. If this is not the case, the input point and, if
necessary, the input angle of the laser beam must be adjusted as described below.

Checking the input point
o Insert the cross hair device into the beam input (1).
o Hold a piece of thermo transfer paper behind the cross hair device.
o Turn on the laser at low power for just long enough for a clearly visible effect (3) to appear
on the thermo transfer paper.
o Check the beam diameter. It must be smaller than the input aperture specified in the data
sheet.
o Check that the laser beam appears in the center of the cross hairs. If not, the input point of
the laser beam needs to be adjusted.
Checking the input angle
o Insert the cross hair device (2) into the beam output and repeat the above steps in this
position.
In subsystems with a spacer, insert the cross hair device in the mounting plate.
o Hold a piece of thermo transfer paper behind the cross hair device.
o Turn on the laser at low power for just long enough for a clearly visible effect to appear on
the thermo transfer paper.
o Check the beam diameter. It must be smaller than the input aperture specified in the data
sheet. If the beam diameter at the beam output is greater than that measured at the beam

Warning:
The laser beam can cause severe injury to the eyes and the skin. Make sure
that all personnel in the laser area are wearing appropriate protective goggles
and, if necessary, protective clothing.
