OWNERS MANUAL | Cobolt Modulated DPSS Lasers | D0342-C JUNE 2016
Safety
General
Cobolt Modulated DPSS Lasers are Class IIIB (CDRH), Class 3B (IEC) laser products emit less than 500 mW of laser
radiation within the visible spectrum. Residual emissions from the pump diode are contained within the laser head
housing via filtering optics. The residual emission does not exceed Laser Class 1.
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. Class 3B 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 on the end product.
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.
