INFRARED
• Infrared can be obtained by a living creature or object that has
the heat
• Thera is can be :
Green House
Aspalt
Sunlight
EVEN...
• Our bodies produce infrared light from the combustion that
produces energy ...
let's see more 
DEFINITION OF INFRA-RED
Infra-Red Electromagnetic Wave is a light not visible and
can not break materials not transparent, that can also be caused by
produce heat components, with wavelengths longer than visible light,
but shorter than radio waves radiation

Discovery
• In 1800 William Herschel
discovered “invisible light”
• It’s energy with all the same
characteristics as visible light,
but is not sensed by the human
eye
• The light Herschel discovered
was just beyond the red part of
the spectrum. So it was named
“infrared”
MICRO
0,7 microns
1000 microns
Infra-Red ray included in electromagnetic wave and stay in to span
frequency 300 GHZ until 40.000 GHZ and has a wavelength between 700 nm (0,7
microns) and 1 mm (1000 microns)
Infra-Red ray yielded by process in hot object and molecule. Have known
that by old hot object of effect of activity (vibration) atomic and molecular is in
assumed to transmit heat wave in the form of infra-red ray. Therefore, infra-red ray is
often referred as heat radiation.

let's see more differences 
Visible:
dark nebula, heavily obscured by interstellar dust
(“Horsehead Nebula”)
Near-Infrared: dust is nearly transparent, embedded stars can be
observed
Mid Infrared: glow from cool dust is directly observable

CHARACTERISTIC INFRA-RED
 Cannot be seen by human being
 Cannot penetrate items which is not transparant
 Can be generated by component yielding heat
 Wavelength of infra-red own adversative relation or
compared to inversed with temperature. When the
temperature increase, then the wavelength decrease

Virtual Laser
Keyboard
• The Virtual Laser Keyboard (Epic Celluon
Magic Cube) is a revolutionary accessory
• The only keyboard that operates in total
darkness) for Iphone, Ipad, Smartphone, &
Tablet PC and any device.
• This tool uses the principle of
infrared waves, which detects heat
changes.
• When we touch type button on the
Virtual Laser Keyboard, the heat
generated from our hands is
converted into a specific code and
sending through your monitor
screen.
Home security systems
In modern times, there
are many products that offer on
a home security system. One of
them is a PIR (Passive InfraRed)
• The passive infrared (PIR) motion detector is one of the most
common sensors found in household and small business
environments.
• The term passive refers to the fact that the detector does
not generate or radiate its own energy; it works entirely by
detecting the heat energy given off by other objects.
• Strictly speaking, PIR sensors do
not detect motion; rather, they
detect abrupt changes in
temperature at a given point.
• As an intruder walks in front of
the sensor, the temperature at
that point will rise from room
temperature
to
body
temperature, and then back
again. This quick change triggers
the detection.
Spitzer Space
Telescope
• The Spitzer Space Telescope (SST),
formerly the Space Infrared Telescope
Facility (SIRTF), is an infrared space
observatory launched in 2003. It is the
fourth and final of the NASA Great
Observatories program.
• the way it works is similar to a thermal
detector, only the components of the tool
in combination with a sophisticated
telescope so that it can obtain the
desired image
• Here are the observations that have
been made by NASA :

Infrared is electromagnetic radiation of a
wavelength longer than visible light, but shorter than
radio wave radiation generated by the electrons in
the molecules vibrate because of heated objects
and has the 1011Hz frequency up to 1014 Hz to 3
range area.. The inventor is Sir Frederick William
Herschel, the astronomer United Kingdom that born
in Germany. Infrared light has many benefits such
as in the areas of health, electronic and
communication technologies, industry, etc.
