SAFETY PRECAUTIONS ON LASER PRODUCT
4. Safety consideration
Use of controls or adjustments or the performance of procedures other
than those specified herein may result in hazardous radiation exposure.
1) Class 3B/IIIb laser products
• MPE (Maximum Permissible Exposure): 2.55 mW/cm
2
(LK-501)
• NOHD (Nominal Ocular Hazard Distance): 8 m (LK-501) from the
aperture.
Follow the instructions mentioned in this manual. Otherwise, injury to the
human body (eyes and skin) may result.
• Do not directly look at or touch the laser beam and its reflection
from a mirror-like surface.
• Do not direct the beam at other people or into areas where other
people unconnected with the laser work might be present.
• Prevent the diffusion of the laser beam.
Make the laser path as short as possible and be sure to terminate it
with a diffusion reflector or diffusion absorber which has proper
reflectance and thermal characteristic.
(It is recommended that you install a protective enclosure.)
• Install the laser product carefully so that the laser beam is not
unintentionally directed at mirror-like surfaces.
• Wear protective eye goggles appropriate for the laser beam
wavelength.
• Do not disassemble this product. Laser emission from this
product is not automatically stopped when it is disassembled.
• Clean the aperture regularly. In addition, stop the emission of the
laser beam when cleaning.
WARNING
CAUTION
2) Class 2/II laser products
Follow the instructions mentioned in this manual. Otherwise, injury to the
human body (eyes and skin) may result.
• Do not stare into the beam.
• Do not direct the beam at other people or into areas where other
people unconnected with the laser work might be present.
• Be careful of the path of the laser beam.
If there is a danger that the operator may be exposed to the laser
beam reflected by specular or diffuse reflection, block the beam by
installing an enclosure with the appropriate reflectance.
• Install the products so that the path of the laser beam is not as
the same height as that of human eye.
• Do not disassemble this product. Laser emission from this
product is not automatically stopped when it is disassembled.
