Guarding; Access Guards; Visor Guards - Domino F Series Product Manual

GUARDING

The following type of guarding, using the recommended materials and
construction techniques, is required to achieve a safe installation.
Never install a fibre laser in such a way that the lens points to a door or in
the direction of an operator.
When designing a housing for a fibre laser always use overlaps where
possible to trap the laser light inside the housing especially for mark on the
fly applications where a product inlet and outlet to the housing are needed.

Access Guards

Access guards are required to prevent direct human access to the laser
beam. In practice, this requires full guarding of the area between, and
including, the laser output lens and the area to be marked on the substrate.

Note: Guarding is required behind the substrate to prevent access to
the laser beam when the substrate is removed, or following
accidental burn through of the substrate.

Visor Guards

Visor guards are required to prevent the escape of scattered radiation.
Often the access guarding can be designed to perform this function without
the need of an extra guard.
