Laser area
For the purposes of accident prevention, the laser area is defined as the area in which the
maximum permitted radiation value can be exceeded. This is generally applicable for class
3B, 3R and 4 lasers. For class 1 to 2M laser devices, a laser area can be produced by focus-
ing the laser beam.
A sufficient beam intensity produces a laser area that covers the entire radiation angle of the
deflection unit and includes the reflection from all objects that can be exposed to the radiation
as a result. Note that even apparently diffuse surfaces can reflect laser radiation and a laser
beam that has been reflected several times can still be dangerous.
The laser area must be indicated by corresponding warning signs or lamps and protected by
appropriate shading and interlock switches.
No flammable or explosive objects or liquids should be located in the laser area.
This operating manual interprets a selection of accident prevention regulations from the point
of view of using laser deflection units in industrial plants. However, the applicable local and
national standards, rules and regulations are binding.
