without the need of an extra guard.

WARNING:

Beam Stop Guard

A beam stop guard is required for applications where guarding material
is fitted within 100mm of the laser lens focal plane. The beam stop is to
prevent burn through of the guard should the laser be repeatedly
operated without the substrate in position. The beam stop must be
capable of absorbing the full output power of the laser for a period of
eight hours and be large enough to cover the complete laser marking
field area.
