Products
in
laser
safety
class
2
have
a
label
like
the
picture
on
the
right
side.
These
products
do
not
require
special
laser
safety.
Sensors
with
laser
output
power
higher
than
1
mW
and
lower
than
5
mW
are
laser
safety
class
3R.
These
products
have
a
label
according
to
FDA
and
IEEE
/
DIN
‐
ISO
regulations,
specifying
laser
class
3R,
laser
wavelength
and
laser
energy.
For
these
products,
protective
means
as
mentioned
above
are
required.
According
to
FDA
/
DIN
‐
ISO
regulations
a
laser
safety
expert
must
be
available
in
the
company
using
such
products.
