This
educational kit has been composed to lead the
students to a careful and safe dealing with lasers.
The kit is excellently useful to learn the classification
of different lasers into the laser safety classes.
The basics and the handling of the standards
VBG, EN60825 will be introduced. All necessary
calculations and determinations will be discussed
and trained:
-
Maximum Permissible Radiation (MPR) for eyes
and skin.
- Minimum Safety Distance from a radiation source
(MSD).
- Demonstration of the damaging effect of laser
radiation.
- Evaluation of pulsed laser systems.
The
different laser radiations have a broad spectral
range from a few nanometer up to some hundred
micrometers and is mostly outside of the visible
spectrum.
The danger of laser radiation to eyes and skin
depends strongly on the time of exposition and
the laser wavelength. This is valid for direct
and even scattered laser radiation too.
The kit is equipped with five different laser sources.
All necessary parameters will be measured by the
students to classify each laser and to determine
their safety limits.
