Laser Apertures
The accessible Class I/Class 1 laser radiation emerges from the aperture in the left hand
side of the sample compartment; the radiation crosses the sample compartment and
enters the detector aperture.
Class I/Class 1 laser radiation exits the external beam port when the port cover is
removed and the external beam is selected. The laser radiation is not accessible at the
port when an external beam accessory is attached. When an external beam accessory is
removed from the instrument, the internal beam path must be selected, or the external
beam port cover must be replaced.
WARNING
Do not stare into any laser beam. Staring into a laser beam
(intrabeam viewing) can cause permanent damage to your eyes.
Radiation Emitted by the Spectrum 100N FT-NIR
The Spectrum 100N FT-NIR quartz halogen bulb, which produces the near infra-red
beam, emits ultraviolet, visible and infrared radiation. The majority of this radiation is in
the infrared region. Do not stare into the beam produced by this bulb.
Measurements of the infrared radiation emitted from the sample area show that exposure
limits recommended by the American Conference of Governmental Industrial Hygienists
(ACGIH) and International Commission on Non-Ionizing Radiation Protection (ICNIRP)
will not be exceeded during normal operation.
