1. 1 LASER SAFETY nLIGHT M4 Microlaser lasers are carefully designed and tested to ensure that they are safe and reliable tools when used properly However nLIGHT M4 Microlasers typically emit light at wavelengths and optical powers that can be extremely hazardous to both people and property if the proper safety guidelines are not followed This danger can be compounded when the output wavelength of laser light is invisible to the naked eye as Is the case with the M4 Microlaser product that emits in the infrared spectrum 1 1 Responsibility for Safety Both the owner and the operator of the laser module are responsible for ensuring that it is assembled into a system and operated in a safe manner The nLIGHT M4 Microlaser is defined as a laser product It is not suitable for direct use and is solely intended to be integrated into a laser product certified by the Purchaser The device lacks mechanical and or safety features that contribute to the safe and proper operation The Purchaser acknowledges that their product must comply with the applicable regulations or standards before it can be sold to an end user 1 2 Laser Classification Government regulations and international standards specify that lasers must be classified according to the output power or energy and the laser wavelength In the U S A the M4 Microlaser is classified as Class IV based on 21 CFR subchapter J part Il section 1040 10 d The M4 Microlaser is classified as Class2. all Class 4 emissions 1 5 Thermal Protection Without proper thermal management the M4 Microlaser can quickly reach temperatures that are dangerous to operators and pose a risk of damaging equipment See the installation section for proper integration guidelines e Thermal management is required for safe and reliable M4 Microlaser operation e See Installation section for further details about thermal management requirements 1 6 Shutter Compliance The M30 Microlaser is intended to be sold to an original equipment manufacturer of electronic products It is the responsibility of that integrator to incorporate into their product a shutter that can block all bodily access to Class 4 laser radiation without turning off the laser The M4 Microlaser is an OEM product and does not have optical shutters Ensure that the laser output is aimed at the intended target prior to turning the laser system ON 1 7 Safety Compliance with Government Requirements The M4 Microlaser laser product does not conform to the United States Government requirements for general laser safety In the U S A it is the responsibility of the buyer to whom the product was sold end manufacturer to comply with all laser safety requirements prior to resale These laser safety requirements are contained in 21 CFR Sub chapter J and are administered by the Center for Devices and Radiological Health CDRH e www fda gov Copyright 2013 nLIGHT Photonics Corpo
