Arc Lamp
The xenon arc lamp has a sapphire lens and a ceramic cover over the anode and
cathode. It operates at high temperatures and the beam contains high levels of ultra-
violet and infrared radiation. It is contained in a housing which acts as a heat sink.
Aspect Ratio
This is the ratio of picture width to picture height (the standard television aspect
ratio is 4x3).
Black body
An ideal body or surface that completely absorbs all light falling upon it with no
reflection.
Brightness
The light intensity of the displayed image.
Cold Mirror
This type of mirror filters infrared light, so that only 'cold' light is reflected. In the
projector it is used to reflect the beam from the lamp into the condenser.
Colour Temperature
The Colour Temperature is the position along the black body curve of the
chromaticity diagram - but takes into account the preset values for colour balance in
the service set-up to take up the variations in the prism.. The projector allows you to
adjust this temperature (i.e. adjust the picture colour) in steps of 100°K from 3000°
to 9900°.
Composite Signal
A signal line that carries information relating to the entire signal, also incorporating
sync pulses.
Contrast
The difference between the dark and light areas of the screen.
