Laser Area

The area in which the maximum permitted radiation value can be exceeded is defined as the laser
area. In general, a laser area is applicable to Class IIIa, IIIb and IV laser systems. A laser area can also
be produced if you focus the beam of a Class I, IIa, or II laser device.

The AGV-SPO can aim the laser beam over an approximately pyramidal volume. When the scan head
is used in conjunction with a laser device that can generate a sufficiently intense beam, a laser area
will be produced that includes the aiming volume as well as the reflections from all objects that can
be exposed to the radiation. It is important to 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 designated by suitable warning signs or lamps and protected by appropriate
shading and interlock switches.
