your computer, on card-mounting brackets, and on the cards themselves. If any one of the 
labels carries a Class A rating, your entire system is considered...

Glossary
ANSI LUMENS —A standard for measuring light output, used for comparing 
projectors.
A
SPECT RATIO —The most popular aspect ratio is 4:3 (4 by 3). Early television and 
computer video formats are in a 4:3 aspect ratio, which means that the width of 
the image is 4/3 times the height.
B
ACKLIT (BACKLIGHT) —Refers to a remote control, or a projector control panel, that 
has buttons and controls that are illuminated. 
Bandwidth— The number of cycles per second (Hertz) expressing the...

76Glossary
Contrast Ratio— Range of light and dark values in a picture, or the ratio between 
their maximum and minimum values. There are two methods used by the 
projection industry to measure the ratio:
1Full  On/Off — measures the ratio of the light output of an all white image (full 
on) and the light output of an all black (full off) image. 
2ANSI — measures a pattern of 16 alternating black and white rectangles. The 
average light output from the white rectangles is divided by the average light...

Glossary77
Maximum Distance— The distance from a screen the projector can be to cast an 
image that is useable (bright enough) in a fully darkened room. 
Maximum Image Size— The largest image a projector can throw in a darkened 
room. This is usually limited by focal range of the optics. 
Metal Halide Lamp— The type of lamp used in many medium and all high end 
portable projectors. These lamps typically have a half-life of 1000-2000 hours. 
That is they slowly lose intensity (brightness) as they are...

78Glossary
Zoom Lens— Lens with a variable focal length that allows operator to move the 
view in or out making the image smaller or larger. 
Zoom Lens Ratio— Is the ratio between the smallest and largest image a lens can 
projector from a fixed distance. For example, a 1.4:1 zoom lens ratio means that a 
10 foot image without zoom would be a 14 foot image with full zoom.
