/ D9 h* `$ m: lQuestion:
9 X0 O5 u7 H" oIs it necessary to always use a 50 mm aperture stop in order to fulfil the requirements for the measuring Condition 1?
Decision:
If the laser beam is well collimated so that the entire radiant power is passing through a 7 mm aperture within 2000 mm distance, it is acceptable to use a 7 mm aperture stop for the purpose of testing according to Condition 1.
& `+ Y. z3 I* k$ jNote: National Certification Bodies shall provide objective evidence that the whole laser beam is captured with the reduced aperture size.
