cables to avoid potential hazards.
W A R N I N G : Wear clean, powder-free gloves when you handle optical components.
Laser Safety
It is the responsibility of the user to provide the necessary conditions for safe operation of a laser system and
to safeguard the surrounding area against the hazards that can be caused by laser radiation. The user must
ensure compliance with all local and national regulations.
Although the scan head by itself does not emit laser radiation, the user must undertake a thorough analysis
of system safety before operating the AGV-HP(O) in conjunction with a laser source. Important information
for performing this analysis is presented in this manual. Additional information may be found in the
corresponding documentation supplied by the manufacturer of the laser source.
Classes of Lasers
The AGV-HP(O) series scan head can be used with a variety of lasers. Each laser is assigned a particular
hazard level, which is indicated by the Laser Class label that is affixed to the device near the location where
laser radiation is emitted. Brief descriptions of each of the various radiation classes are presented in the
table below.
Note that in addition to the dangers of radiation, lasers may pose further dangers, such as the risk of
electrical shock or the generation of poisonous fumes.
Classifications of Laser Devices
Class Danger
Class I Inherently safe; no possibility of eye damage during normal operation.
Class IIa Requires in excess of 1000 seconds of continuous viewing to cause eye dam-
age.
Class II The blink reflex will prevent eye damage, unless the person deliberately stares
into the beam for an extended period of time.
Class IIIa
Mostly dangerous in combination with optical instruments which change the
beam diameter or power density. However, even without optical enhancement,
direct contact for over two minutes may cause eye damage.
Class IIIb Direct exposures of 0.01 second or less may cause eye and skin damage.
Class IV Direct or scattered radiation without optical enhancement may cause eye and
skin damage.

AGV-HP(O) Hardware Manual Laser Safety

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 may also be produced
by focusing the beam of a Class I, IIa, or II laser device.
The AGV-HP(O) has the capability of aiming the laser beam over an approximately pyramidal volume. When
the scan head is used in conjunction with a laser device capable of generating 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.
Figure 1: Laser Area of an AGV-HP(O) Scan Head
Laser Shutter
A laser attenuator (beam shutter) is a mechanical or electrical device that blocks the emission of laser
radiation. It is a requirement for most classes of laser systems. The attenuator must be available for use at
all times during operation of the laser system. Power switches and key controls do not satisfy the attenuator
requirement.
The AGV-HP(O) scan head does not include a laser attenuator, and therefore it cannot block or weaken the
laser beam. Due to the unique properties of each laser, it is the user’s responsibility to incorporate an
appropriate shutter as per any and all applicable regulations in order to prevent unwanted emission of the
laser beam.
Laser Area AGV-HP(O) Hardware Manual
8 www.aerotech.com

The beam shutter should be fitted between the laser source and the scan head (refer to Figure 1).
W A R N I N G : Do no stare into the laser beam, place your body parts in the beam path, or
expose yourself to reflections from powerful beams.
W A R N I N G : Only a Class 1 HeNe laser is recommended for performing alignments. If this is
not possible, use the lowest power setting on the available laser and employ remote beam
sensing techniques.
W A R N I N G : Wear eye protection. The danger to your eyes increases when optical
instruments are used in conjunction with the scan head.
