Camera and Technology Overview

Background

The Thermal-Eye™ 250D Camera is a part of the L-3
Communications Infrared Products (L-3 CIP) Thermal-Eye™
product line. Thermal-Eye™ 250D is a revolutionary thermal
imaging system that is the result of many years of research and
experience. L-3 CIP has long been a leader in the production
and development of night vision systems based on infrared
thermal imaging. Over the years, L-3 CIP’s experience has
lead to many improvements in performance and reliability of
night vision systems. In an effort to make this technology
more affordable, L-3 CIP’s engineers and scientists developed
a unique way of translating infrared energy into electronic
signals. This innovation, combined with experience in
developing and building military night vision systems, has
lead to the creation of Thermal-Eye™ 250D Camera. Now
L-3CIP is providing affordable commercial thermal imaging
solutions for law enforcement, marine, security, and other
commercial uses while continuing to supply other special
products that meet the particular needs of the military.

Customer Service

At L-3 Communications Infrared Products (L-3 CIP), we have
made considerable investment in training our personnel, and
we are equipping and training our dealers to help you install
and apply our Thermal-Eye™ products. If you have questions
or comments, please call Customer Service at 800-990-3275.

Infrared Imaging and Applications

Visible light, the rainbow of colors that can be sensed by the
human eye, is electromagnetic radiation within a certain
frequency band. ‘Infra-‘ means ‘below’ and ‘red’ is the lowest
frequency in the visible spectrum. Hence, ‘infrared’ (or ‘IR’)
refers to that range of electromagnetic wavelengths just below
that capable of sight by the human eye. In the IR range,
energy from a scene is not sensed by sight (light) but rather by
temperature.

Camera and Technology Overview (cont’d)

Most objects that you see are not radiating visible light but
instead, are reflecting light radiated from another source.
Most objects have to be heated to extreme temperatures before
they radiate energy in the visible light spectrum. However,
energy in the infrared range is being radiated by all objects
that are above absolute zero (-459F). Hence, everything has a
thermal signature, regardless of light conditions.

As the frequency of electromagnetic energy increases, the
length of the waves decreases. Infrared shares many of the
properties of visible light, but its diffe rent wavelength has
several other unique characteristics. For instance, materials
that are opaque to visible light may be transparent to infrared,
and vice–versa. Infrared is less subject to scattering and
absorption by smoke, smog, or dust than visible light, and
infrared cannot be seen by the human eye.

Different objects give off varying amounts of infrared,
depending on the temperature of the object and also on a
characteristic called emissivity.. Heavy rain, fog, and other
environmental conditions may degrade infrared imagery, but
an infrared thermal imager will still penetrate these obscurants
better than the human eye, or other night vision technologies.

The Thermal-Eye 250D infrared detecting system
distinguishes between very small differences in thermal
(infrared) radiation, converts it to electrical signals, amplifies
those differences , and reproduces them correspondingly in the
visible light (video) range. Powerful advantages are achieved
in being able to turn a pitch black night into a black and white
TV image of the scene. As your infrared knowledge and
experience grows, further applications will develop as you
recognize heat clues beyond the naked eye in both day and
night conditions.

Battery Care and Use Instructions

READ INSTRUCTIONS CAREFULLY
BEFORE USING BATTERY.

Instructions for Best Performance

• The nickel metal hydride battery needs to be

charged before use. Refer to “Battery
Conditioning”.

• When this battery is charged for the first time, the

charger may indicate that charging has been
completed after just 10 to 15 minutes. This is
normal and can happen with any rechargeable
battery when it is first charged, or, if it has been
stored unused for a prolonged period. Simply
remove the battery from the charger and repeat
the charging procedure. There is no need to
discharge the battery between these charges.

• Best charging results are obtained at normal room

temperature, 70 ± 8 °F (21 ± 2 °C). Charging
beyond this range is permissible but will not
result in the battery’s full capacity being reached.
Charging at temperatures below 50 °F (10 °C) or
above 95 °F (35 °C) is not recommended.

• It is normal for the battery to become warm

during charging or after use.

• Nickel Metal Hydride batteries do not develop a

‘memory effect’ typical of other rechargeable
battery types. Therefore, it is not necessary to
fully discharge the nickel metal hydride battery
before recharging, nor is it necessary to
periodically “recondition” the battery. You can
top–off the charge at any time.

Note that performing a refresh or discharging a
nickel metal hydride battery, though not required,
will not harm the battery.

Battery Care and Use Instructions (cont’d)

• All rechargeable batteries will gradually lose their

charge over time when they are left in storage. If
this battery will be left in storage for more than a
few days prior to use, a top–off charge to regain
full capacity is recommended.

• Remove the battery from equipment, charger, or

AC adapter when not in use. Store in a cool dry
place.

• Wipe the metal terminals with a soft, dry cloth if

they become dirty.

Safety Precautions

• Do not disassemble or attempt to open the battery

under any circumstances.

• The battery can explode, leak, or catch on fire if

heated or exposed to fire or high temperatures.

13

• Do not short circuit the battery by directly

connecting the metal terminals (+, -). Be certain
that no metal objects such as coins, paper clips,
etc. touch the terminals.

• Only use the charger recommended by the device

manufacturer.

Instructions to Avoid Battery Damage

• Do not drop this battery or subject it to

mechanical shock.

• Use the battery only with equipment that specifies

its use.

Battery Care and Use Instructions (cont’d)

Battery Conditioning

Battery Charger Battery

The battery provided comes fully discharged and
requires some conditioning prior to use. We
recommend conditioning your new battery as follows:

1. Plug battery charger into AC outlet or car

battery adapter.

• Power LED will light, indicating the

charger/refresher is powered by either
the AC adapter or the DC car plug.

2. Insert battery in battery charger adapter.

• Place battery on battery charger with

about 1/8 inch hanging over edge.

• Press battery down against spring–

loaded pins and slide battery in to place.

3. Press refresh button to discharge and then

charge the battery.

• Charge LED will light (amber),

indicating that the unit is discharging a
battery.

4. When battery begins fast-charging, charge

indicator will light (red).

5. When battery is fully charged, the charge

indicator will light (green).
