18 Object group settings
The value set for “Laser power correction [+/-%]” is applied to the laser power of the step
& repeat object. The laser power of the step & repeat object is the same as the laser
power of the marking object for which the step & repeat function is applied.
In case that you corrected the laser power of the marking object under “Object settings” >
“Laser power correction [%]”, the value set for “Laser power correction [+/-%]” in “Step &
repeat fine adjustment” is applied to the corrected laser power result.
Examples
‒ The laser power is set to “50” in the “Laser settings” tab and “100” is set under
“Object settings” > “Laser power correction [%]”. The laser power of the step & repeat
object is the result of the following calculation: 50 x 100% = 50 .
To correct the laser power of an element (e.g. “Single step”), select “Fine adjustment”
and “Add”. In the dialog, enter “20” for “Laser power correction [+/-%]”.
The corrected laser power of the element (e.g. “Single step”) is the result of the
following calculation: 50 x 120% = 60
‒ You can specify several sets of parameters in the “Step & repeat fine adjustment”
dialog. In the following example, there are two sets of parameters, one for the
first column and another one for the first row. For the first column, specify a laser
correction value of “10”. For the first row, specify a laser correction value of “20”.
The following drawing shows that for the step which is at first position in the first
row and column, the specified parameter sets overlap. In this case, the laser power
correction value is the result of adding up the values specified for each parameter
set. The following calculation is used: 100 + 20 + 10 = 130 [%]
