3.1.21 Laser energy
source. Any device intended for use in conjunction
with a laser to supply energy for the operation of the laser. General energy
sources such as electrical supply mains or batteries shall not be considered
to constitute laser energy sources.
product. Any manufactured product or assemblage of
components which constitutes, incorporates, or is intended to
incorporate a laser or laser system. A laser or laser system which is intended
for use as a component of an electronic product shall itself be considered a
radiation. All electromagnetic radiation emitted
by a laser product within the spectral range specified in paragraph 3.1.38
and is produced as a result of controlled stimulated emission.
system. A laser in combination with in appropriate
laser energy source with or without additional incorporated components. With
respect to a weapons system, the terminology “laser subsystem” should be
construed to have the same meaning.
3.1.25 Laser controlled
area. Any area which contains one or more lasers
where the activity of personnel is
subject to control and supervision for the purpose of protection from radiation hazards associated with laser
Light. See visible radiation (in paragraph
flux. Quantity derived from radiant flux in units
of lumens by evaluating the radiation
according to photopic vision for a CIE standard photometric observer.
(lm)-. The derived SI unit of luminous flux
emitted in a solid angle of 1 steradian
by a uniform source of luminous intensity of 1 candle. One lumen equals one candle steradian (1 lm = 1 cd.sr).
transmittance. Ratio of the transmitted luminous
flux to the incident luminous flux.
(lx). SI unit of illuminance (illumination) of a
surface of 1 square meter in area from a
source of uniformly distributed luminous flux of 1 lumen (1 1x = 1
