General

This normative annex addresses the arrangement, installation and use of guided beam delivery systems. Laser beams can be propagated through air, gas or vacuum, whether enclosed or not (free space), and through fibre optic cables in laser processing machine applications.

This annex applies to the protective measures implemented to protect personnel against laser radiation hazards for guided beam delivery systems after the output coupler and/or the protective housing of the laser product (the requirements of which are specified in IEC 60825-1).This annex is intended to compliment the requirements applicable to the laser process enclosure (which are specified in this document and in ISO 11553-1). This annex also provides methods for assessing the risks (including reasonably foreseeable use, abuse and misuse) and provides examples of control measures to meet the normative requirements of IEC 60825-1 and this document.

This annex does not apply to beam delivery systems inside the protective housing of the laser.

This annex does not apply to beam delivery systems used in medical or communications applications.
