1.3. WARNING AND INFORMATION SYMBOLS
This chapter includes all terms and symbols used in this instruction manual or on the laser system to
alert both operating and service personnel to the precautions concerning the care, use, and handling of
Certain terms are used throughout this manual or on the equipment labels. Please familiarize yourself
with their definitions and significance.
1.3.2. POSSIBLE PERSONAL INJURY WARNING
This product emits infrared radiation at a wavelength of 10.6 µm. Direct or indirect exposure to laser
radiation may cause serious damage to the cornea, therefore it is mandatory to wear protective viewing
goggles in areas exposed to the laser beam. Goggles protect against scattered radiation or reflections
from metal surfaces. Protective goggles that block 10.6µm CO2 laser radiation are available from
RADIATION VIEWING CONDITIONS
The laser exiting the resonator is considered an intense monochromatic light source. Due to these
features it can be seen as a source of high luminosity.
This means that its image is focused on the retina at a point of high-density power. If the beam diverges
and is dispersed on a non-reflective screen, then there would be an "extended view" of the image, with a
decisively less dangerous power density. So there are different types of radiation views based on the
access to the radiation and consequently different degrees of danger.
Direct view of the Laser beam:
This type of view is the most dangerous and can occur at the exit of the laser aperture after having
removed the lens. It must be avoided! Use of protective goggles is not sufficient to protect against direct
view of the beam.
Hazards that could result in serious personal injury or death.
Hazards or unsafe practices that could result in serious personal
injury or death.
Hazards or unsafe practices that could result in minor personal
injury or product damage.
