Fiber Coupled Option
All safety recommendations in section 2 are also valid for the Cobolt Skyra™ fiber coupled laser heads. Additionally,
heat generated from absorption of laser radiation by particles on the fiber end may increase the probability of ignition
hazards in certain environments. Always clean the fiber end before turning on the laser. In systems where the beam
is exposed, fiber end must be mounted < 2 m from the emission warning LED. 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.
Accessible emission information for Cobolt Skyra™ laser lines
The table below describes the irradiance in W/cm

and appropriate level of eye protection in terms of optical density
(OD) for each product line. Using a multi-line laser requires a combination of eye protection that is specifically tailored
to the device configuration. Be sure to consider all available wavelengths and power levels when selecting eye
protection.
