General Information
This laser system is a Class 4 laser
. It is an Nd:YAG solid-state laser with a
high optical output power. This invisible laser radiation has a wavelength of 1064
nm (near infrared range). The visible secondary radiation can cause dazzle
effects if watched for any length of time.
The laser radiation generated by this device is not visible to the human eye due
the wavelength involved.
The eye is particularly endangered by this infrared (invisible) laser
radiation, because its effect is multiplied by the eye lens and
focused on the retina. The high radiation intensity on the retina
causes extreme local heating and burns the tissue of the retina.
This results in reduction or even loss of eyesight. Therefore, when
working with direct access to the laser beam (maintenance, repair),
always wear eye protection.
Always follow the OSHA regulations, ANSI Z136.1-2014, Safe Use of Lasers, on
accident prevention for laser radiation or the equivalent national or international
regulations (e.g. IEC 60825-1:2014) working with the laser equipment.
If a modification by the user affects any aspect of the performance
data or intended functioning, as described in the relevant standards, of
a previously classified laser device, the person or organization that
undertook the modification is responsible for obtaining a new
classification and new labeling for the device. This person or
organization then assumes the status of “manufacturer.”
The mandatory protective laser eye wear, with an OD >6.5 (Order No. 444-001),
provide protection against direct, reflected and scattered radiation. But even if
you are wearing protective laser eye wear, never look directly at the beam.
Intense laser radiation is capable of destroying the protective filter. Danger exists
through: directed radiation, reflected radiation and/or diffused scattered radiation.
(
Note
: In
Class 4
operation of the product, the protective laser eye wear will
normally protect against the hazards of collateral radiation (e.g. ultraviolet,
visible, infrared radiation). However, if a concern exists that the accessible
collateral radiation might be hazardous, the end user is responsible to consider
the MPE values required for the various materials being processed.)
