3.0 Safety Issues
3.1 Laser Safety
ULS OEM lasers are sold as components and therefore are not required to conform to U.S. or
European safety regulations. It is the responsibility of the buyer to design and certify any
equipment incorporating a ULS OEM laser to meet all local safety regulations prior to sale to
the public. The texts of these regulations are available from the respective governing bodies
of the countries the equipment is to be sold into.
Any personnel working with or around open lasers must be aware of the following:
 Exposure to the laser beam may cause physical burns and can cause severe eye
damage. Proper eye protection should be used at all times. All eye protection should
be appropriate for the radiation wavelength generated by the laser in use.
 Exposure to the laser beam may cause ignition of volatile or combustible
materials. Do not use lasers in the presence of these types of materials.
 Never look directly into the laser output port.
 Interlock all rooms in which open beams may be present and post appropriate
warnings on or near the doors. Access to these rooms should be limited to properly
trained technicians when lasers are in use.
 Use appropriate protective coverings over all beam paths whenever possible.
 Lasers and optical elements should be positioned to keep the beam and
reflections below eye level.
Notice: For more information on EMI standards, refer to local EMI safety regulations.
3.2 Electrical Safety
ULS lasers operate at 48 VDC, which is below the voltage limit that is considered dangerous
by most safety standards. However, the lasers draw large amounts of current and the power
supplies needed to provide the 48 VDC usually require 90-240 VAC to operate. For these
reasons, proper safety precautions should be taken with every portion of the electrical
system.
Notice: For more information on EMI standards, refer to local EMI safety regulations.

3.3 Electromagnetic Interference
ULS OEM lasers are sold as components and therefore are not required to conform to all
U.S. or European safety regulations regarding EMI. It is the responsibility of the customer to
design and certify any equipment incorporating a ULS OEM laser to meet all local safety
regulations prior to sale to the public. However, testing by ULS has demonstrated that with a
properly selected power supply and line filtering all ULS OEM lasers will pass the relevant
U.S. and European EMI standards for Class A equipment. See Section 5.3 for more
information.
Notice: For more information on EMI standards, refer to local EMI safety regulations.
3.4 Contacts for Safety Information
It is the responsibility of the integrator to meet all applicable safety standards required
by the authorities of the region that the unit will be operating in. Below is a list of useful
