AGV3D Hardware Manual
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 work area against the dangers 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 they operate the AGV3D 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 AGV3D 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 can pose further dangers, such as the risk of
electrical shock or the generation of poisonous fumes.

Danger
Inherently safe; no possibility of eye damage during normal operation.
Requires in excess of 1000 seconds of continuous viewing to cause eye
damage.
The blink reflex will prevent eye damage, unless the person deliberately
stares into the beam for an extended period of time.
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 could cause eye
damage.
Direct exposures of 0.01 second or less could cause eye and skin damage.
Direct or scattered radiation without optical enhancement could cause eye
and skin damage.
