Beam Hazards
Eye and skin exposure to direct or reflected laser light is hazardous and may be extremely harmful. Always wear eye
protection appropriate to the beam wavelength and intensity. Lasers may pose a risk of igniting flammable materials
and in event of ignition gasses and fumes may be generated. All equipment used in close proximity to the laser beam
should be suitably fire resistant and the facility should be properly ventilated. It is advised to perform a risk
assessment for the facility and equipment prior to using the laser. In the case of integration into a larger system, laser
safety compliance must be evaluated in the end product.
WARNING Remove all watches, rings, and other reflective jewelry before working with lasers.
Always wear the appropriate eye protection from the wavelengths integrated into the system.
Verify the accessible emission wavelength and power before operating. Never look directly into
a laser beam.
The device must be handled by skilled personnel experienced with lasers, in a laboratory environment and with access
to adequate laser safety equipment. The laser head clearly displays a yellow warning label that shows the location of
the laser beam aperture. This label must be visible unless the laser beam is totally enclosed. If the laser does not
function, do not attempt to open any part of the device, or the warranty will be voided. Call or e-mail your local Cobolt
representative for consultancy and to request an RMA number (see back cover for contact information).
Laser radiation may ignite flammable materials and combustible gasses in the beam path and, in event of ignition,
fumes may be generated. All equipment used in close proximity to the laser beam should be suitably fire resistant and
the facility should be properly ventilated.
CAUTION Use of controls or adjustments or performance of any procedures other than those
specified herein may result in exposure to hazardous radiation.
The equations below describe how to use the nominal output power (mW) and beam area to calculate the irradiance
(W/cm2) and how to use the Warning label (Max) power (mW) and the Accessible Emission Limit (AEL) (mW) per laser
safety standard IEC 60825-1:2014 to calculated the required optical density (OD) for eye protection per wavelength.
