Maintenance
The M2D Laser-Scanners are virtually maintenance free. The Scanners are optical measurement tools,
which sometimes need cleaning and inspection from time to time. Cleaning the front window should be
done with a soft, clean cloth. Do not use scratching tools, concentrated solvent liquids are aggressive
chemicals. Dirt should be removed with 15 ... 20 % of isopropyl a distilled water or cleaning benzine.
Finger prints will cause additional noise in the scan profiles, keep your front windows clean!

All
standard
M2-iLAN-Laser scanners models are class 2 / 2M. The emitted laser radiation is below 1 mW.
According to international standards, this amount of laser radiation is not dangerous to the eye. When the
laser beam touches the human skin, this is not giving a problem.
Scanner models having higher laser power are clearly marked with sticker stating the maximum laser power
and laser safety class.
The scanner has a optic system dispersing the laser energy: the line projector distributes the laser energy to
an angle of 20 or 30°. This means, the energy gets very weak in a distance of
a few inches from the laser front window. When the laser is shining against a
mirroring device, the laser power will be reflected and highly visible to the eye,
yet not dangerous.
Products of laser class 2 have a yellow / black label as pictured on the right
side.
a few general rules which may help to use controls, adjustments of performance
and recommended practice to avoid any hazardous radiation exposure:
never
do look into the laser beam
never direct the laser beam against any other person
before cleaning switch off the Laser Scanners
use a piece of paper when you search for the laser beam
never use a mirroring device close to the laser output
always
use
automatic shutter
mode
provide a shield for the scanners vision range
(protection cover or dark plastic glass)

Position of Laser output and labels on the scanner
The Laser output is marked with an arrow on the case.
The yellow label indicates laser power and wavelength.
The table on the following page lists the typical laser parameters.
