    1. LASER SAFETY 1.1. LASER TYPES There are different types of lasers according to the medium of photon propagation (gas, solid, liquid, etc.) contained inside the laser tube and the excitation mechanism used to cause the laser process. As a result, laser emissions of different wavelengths (energy content and power) are obtained.

  • Page 13: Laser Safety Standards

    1.2. LASER SAFETY STANDARDS The Laser Marker is fitted with basic safety features at the point there might be risk of laser emission if the allowed AEL limit is exceeded. The Laser Marker is equipped with a protective housing which, except for the laser aperture, prevents human access to laser emission exceeding Class I.
  • Page 14 EMISSION SAFETY OF LASER PRODUCTS, EQUIPMENT CLASSIFICATION, REQUIREMENTS AND USER’S GUIDE. Safety devices and protections supplied by HITACHI will not necessarily meet requirements of the Customer’s Local Factory Inspector, Laser Safety and Country Regulations and no warranty or representation is given or made that they comply with any statutory or other requirement. No liability is accepted by HITACHI in this respect.

  • Page 15: Safety Switches

    Making this protective housing is the responsibility of the installer in each country. The housing delivered by HITACHI may not be enough, and each client must adapt the housing to its production line, because the final protection must be a closed protection, and the housing delivered by HITACHI may not be completely closed.

    The Optical Risk Nominal Distance (O.R.N.D.) for Laser Markers of HITACHI can be over 20m for direct or reflected radiation, and over 1m for Dispersive radiation.

  • Page 17: Possible Personal Injury

    If exposed to intense laser radiation, even briefly, or to less intensity but longer duration, both the cornea and the retina can be burned and irreparably and permanently damaged. Direct exposure to focused radiation can burn the skin. In addition, it is necessary to bear in mind that there may be collateral ultraviolet radiation along with the main radiation.

LASER is the acronym of Light Amplification by Stimulated Emission of Radiation. Stimulated emission of light is a phenomenon in which atoms are excited by photons (light corpuscles) to emit photons, which in turn amplify light continuously by the electron avalanche effect that excites other atoms.
