Beam paths
The beam emitted by each Class 1M and Class 2M laser product classified under condition 1 of table 10, each
Class 3R laser product emitting energy outside of the 400nm to 700nm wavelength range, and each Class 3B or
Class 4 laser product should be terminated at the end of its useful path by a diffusely reflecting material of
appropriate reflectivity and thermal properties or by absorbers.
Open laser beam paths should be located above or below eye level where practicable.
The beam paths of Class 3R laser products emitting energy outside of the 400nm to 700nm wavelength range
and Class 3B or 4 laser products should be as short as practicable, should have a minimum number of
directional changes, should avoid crossing walkways and other access routes, and should, where practicable, be
enclosed. The beam enclosure (for example, a tube) should be securely mounted but preferably not rigidly
attached to (or provide support for) beam-forming components.
