Risks of ultraviolet exposure
Do not aim the UV light at anyone.
Do not look directly into the light.
Always wear protective goggles, full-face shield and skin protection clothing and
gloves when using the light source.
• Light is subdivided into visible light, ranging from 400 nm (violet) to 700 nm (red);
longer infrared, “above red” or > 700nm, also called heat; and shorter ultraviolet
radiation (UVR), “below violet” or < 400nm. UVR is further subdivided into UV-A
or near-UV (320–400 nm), also called black (invisible) light; UV-B or mid-UV
(290–320 nm), which is more skin penetrating; and UV-C or far-UV (< 290 nm).
• Health effects of exposure to UV light are familiar to anyone who has had sunburn.
However, the UV light level around some UV equipment greatly exceeds the level
found in nature. Acute (short-term) effects include redness or ulceration of the skin.
At high levels of exposure, these burns can be serious. For chronic exposures, there
is also a cumulative risk of harm. This risk depends upon the amount of exposure
during your lifetime. The long-term risks for large cumulative exposure include
premature aging of the skin, wrinkles and, most seriously, skin cancer and cataract.
• Damage to vision is likely following exposure to high-intensity UV radiation. In
adults, more than 99% of UV radiation is absorbed by the anterior structures of the
eye. UVR can contribute to the development of age-related cataract, pterygium,
photodermatitis, and cancer of the skin around the eye. It may also contribute to
age-related macular degeneration. Like the skin, the covering of the eye or the
cornea, is epithelial tissue. The danger to the eye is enhanced by the fact that light
can enter from all angles around the eye and not only in the direction of vision. This
is especially true while working in a dark environment, as the pupil is wide open.
The lens can also be damaged, but because the cornea acts as a filter, the chances
Caution:
ultraviolet light. Exposure to these radiations, even
reflected or diffused, can result in serious, and
sometimes irreversible, eye and skin injuries.
Overexposure to ultraviolet rays threatens human
health by causing:
This instrument is used in conjunction with
• Immediate painful sunburn
• Skin cancer
• Eye damage
• Immune-system suppression
• Premature aging

are reduced. This should not lessen the concern over lens damage however, because
cataracts are the direct result of lens damage.
Burns to the eyes are usually more painful and serious than a burn to the skin. Make
sure your eye protection is appropriate for this work. NORMAL EYEGLASSES OR
CONTACTS OFFER VERY LIMITED PROTECTION!
Warning:
UV exposures are not immediately felt. The
user may not realize the hazard until it is too late and
the damage is done.
Training
For the use of UV sources, new users must be trained by another member of the
laboratory who, in the opinion of the member of staff in charge of the department, is
sufficiently competent to give instruction on the correct procedure. Newly trained users
should be overseen for some time by a competent person.

Additional risks of xenon lamps
Warning:
are dangerous.
Please read the
Among the dangers associated with xenon lamps
are:
• Burns caused by contact with a hot xenon lamp.
• Fire ignited by hot xenon lamp.
• Interaction of other nearby chemicals with intense ultraviolet, visible, or infrared
radiation.
• Damage caused to apparatus placed close to the xenon lamp.
• Explosion or mechanical failure of the xenon lamp.
following precautions.
Xenon lamps
Visible radiation
Any very bright visible light source will cause a human aversion response: we either
blink or turn our head away. Although we may see a retinal afterimage (which can last
for several minutes), the aversion response time (about 0.25 seconds) normally protects
our vision. This aversion response should be trusted and obeyed. NEVER STARE AT
ANY BRIGHT LIGHT-SOURCE FOR AN EXTENDED PERIOD. Overriding the
aversion response by forcing yourself to look at a bright light-source may result in
permanent injury to the retina. This type of injury can occur during a single prolonged
exposure. Excessive exposure to visible light can result in skin and eye damage.
Visible light sources that are not bright enough to cause retinal burns are not
necessarily safe to view for an extended period. In fact, any sufficiently bright visible
light source viewed for an extended period will eventually cause degradation of both
night and color vision. Appropriate protective filters are needed for any light source
that causes viewing discomfort when viewed for an extended period of time. For these
reasons, prolonged viewing of bright light sources should be limited by the use of
appropriate filters.
The blue-light wavelengths (400–500 nm) present a unique hazard to the retina by
causing photochemical effects similar to those found in UV-radiation exposure.
Infrared radiation
Infrared (or heat) radiation is defined as having a wavelength between 780 nm and 1
mm. Specific biological effectiveness “bands” have been defined by the CIE
(Commission International de l’Éclairage or International Commission on Illumination)
as follows:
• IR-A (near IR) (780–1400 nm)
• IR-B (mid IR) (1400– 3000 nm)
• IR-C (far IR) (3000 nm–1 mm)
0-11
Fluorolog-3 v. 3.2 (2 May 2008) Introduction

The skin and eyes absorb infrared radiation (IR) as heat. Workers normally notice
excessive exposure through heat sensation and pain. Infrared radiation in the IR-A that
enters the human eye will reach (and can be focused upon) the sensitive cells of the
retina. For high irradiance sources in the IR-A, the retina is the part of the eye that is at
risk. For sources in the IR-B and IR-C, both the skin and the cornea may be at risk from
“flash burns.” In addition, the heat deposited in the cornea may be conducted to the lens
of the eye. This heating of the lens is believed to be the cause of so called “glassblowers’ ” cataracts because the heat transfer may cause clouding of the lens.
• Retinal IR Hazards (780 to 1400 nm): possible retinal lesions from acute high
irradiance exposures to small dimension sources.
• Lens IR Hazards (1400 to 1900 nm): possible cataract induction from chronic lower
irradiance exposures.
• Corneal IR Hazards (1900 nm to 1 mm): possible flashburns from acute high
irradiance exposures.
Who is likely to be injured? The user and anyone exposed to the radiation or xenon
lamp shards as a result of faulty procedures. Injuries may be slight to severe.

a A source of radiation
produces photons.
b The beam of light is
filtered by an
excitation
monochromator that
allows a single
wavelength of light to
reach the sample.
Controller
(SpectrAcq)
c In the sample
compartment, the
sample responds to the
incoming radiation.
d The resulting radiation is filtered by an emission monochromator that feeds
the signal to a photomultiplier detector.
e By stepping either or both monochromators through a wavelength region,
and recording the variation in intensity as a function of wavelength, a
spectrum is produced.
f The spectrofluorometer components (monochromators, sample-
compartment module, accessories) are connected to a controller (the
“SpectrAcq”), which, in turn, transfers information to and from the host
computer. The host computer may be attached to a printer or plotter.

Fluorolog-3 v. 3.2 (2 May 2008) System Description
Basic components
Monochromators
The Fluorolog®-3 comes equipped with either a single- or double-grating monochromator in
the excitation and emission positions. Double-grating monochromators offer a significant
increase in sensitivity, resolution and stray-light rejection.
Sample compartment
The standard sample-compartment module is a T-box, which provides efficient throughput
with a choice of standard right-angle emission collection or optional front-face emission
collection. The sample-compartment module comes equipped with a silicon photodiode
reference detector to monitor and compensate for variations in the xenon lamp output.
Detector
The standard detector offered on the Fluorolog®-3 is the R928P photomultiplier tube, which
provides sensitive spectral characterization in the UV through the visible.
Accessories
Fluorolog®-3 spectrofluorometers offer sampling accessories to increase flexibility, and
extend their applications to techniques such as polarization measurements or
phosphorescence lifetimes.
