4.8.3 Effective resolution for blanking
The effective resolution of an optical system depends on both its optical components and
on its configuration. The effective resolution cannot be higher than the highest possible
physical resolution of the system. However, it can be reduced by the configuration, e.g. by
blanking beams.
In conjunction with size tolerance, the effective resolution is reduced at the edges of the
blanked areas. For blanking with size tolerance, the effective resolution depends on the
physical resolution and the size tolerance chosen.
Check the safety distance!
When using floating blanking with increased size tolerance, the required safety distance
will depend on the effective resolution (see Tab. 10).
 If required, recalculate the safety distance and readjust it on the machine.
Example: – physical resolution 14 mm
– size tolerance –2 beams
– effective resolution 22 mm
Calculate the safety distance with a resolution of 22 mm (see page 37).
 Mark the effective resolution on the information label “Operation with blanking
combined with size tolerance …” on the related sender and receiver.

Warning: During operation with “Blanking” combined with “Size tolerance”, the safety
distance that corresponds to the modified resolution is to be observed.
