Installation
Checking the input point
o Place a piece of thermo transfer paper behind the cross hair device (A).
o Insert the cross hair device at position (A).
o Turn on the laser at low power for just long enough for a clearly visible effect to appear on
the thermo transfer paper (C).
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 Place a piece of thermo transfer paper behind the cross hair device (B).
o Insert the cross hair device in the lens holder.
o Insert the lens holder in its slot.
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
input, this indicates excessive divergence of the laser beam. In this case, reduce the beam
diameter, e. g. by using beam expander with lower amplification.
o Check that the laser beam appears in the center of the cross hairs. If not, the input angle of
the laser beam needs to be adjusted.
Optimizing settings
o Repeat the entire adjustment process until optimum laser beam input point and input angle
settings are achieved.

Assembly
o Assemble the linear translator and the focusing lens in vice versa order as described in the
disassembly ( page 17).
o You must now set the field size ( page 21, Adjusting the field size).
