The accessible laser radiation lies in the visible spectral range (400
nm to 700 nm). It is also not dangerous for the eyes at a short
exposure time (up to 0.25 s). Additional radiation components
outside the wavelength range of 400 - 700 nm comply with the
conditions for Class 1.
The power of the lasers of Class 2 is limited to 1 mW. The eye is
adequately protected against damage through incidental short-term
looking into the radiation by the eyelid closure reflex that occurs
within 0.25 s due to the dazzling effect of the radiation. This also
applies if optical instruments are present in the beam path.
ā Avoid intentional, sustained looking into the beam path.
If the laser also emits radiation of other wavelengths, these must be
completely harmless to the eyes.
The accessible laser radiation lies in the visible spectral range of
400 nm to 700 nm. It is not dangerous for the eyes at a short
exposure time (up to 0.25 s), as long as the cross section is not
reduced by optical instruments (magnifying glasses, lenses,
telescopes, etc.). Additional radiation components outside the
wavelength range of 400 - 700 nm comply with the conditions for
Class 1M.
Lasers with lower power up to 1 mW. They are not harmful to the
naked eye due to the eyelid closure reflex. Eye damage can occur if
an optical instrument is present during the exposure.
The accessible laser radiation lies in the wavelength range from
302.5 nm to 106 nm and is dangerorous for the eyes. The power
respectively the energy is a maximum of five times the limit value of
the permissible radiation of Class 2 in the wavelength range from
400 nm to 700 nm.
The lasers of this Class are in principle dangerous for the eyes. The
level of danger is limited in that the power in the visible range may
not exceed 5 mW and outside the visible range must not exceed
five times the power of Class 1 lasers.
The accessible laser radiation is dangerous for the eyes and in
specific cases also for the skin.
The radiation of Class 3B lasers (medium power) is dangerous for
the eyes, not only with direct exposure but also with exposure to
reflected radiation. In the upper power range, these lasers can also
damage the skin. The power is limited to 500 mW.
