The AUTO -ZOOM lens
.. for Vidicon TV Cameras
5 to 1 Variable Focal Length (10 to 1 with a simple lens change).
Completely motorized. Zoom, focus and iris remotely controlled.
Fills Vidicon format. No vignetting as with standard 16mm movie lens.
The AUTO -ZOOM TV16 is a high resolution,
5 to 1 variable focal length lens for use with
Vidicon TV cameras. Its remote control, motor -
driven focus and zoom permit smooth, steady
tracking with sharp focus throughout the entire
range. The AUTO -ZOOM lens system is fully corrected
and suitable for color television work.
One Camera Does The
Work Of Two -A single
stationary TV camera equipped with the new
AUTO -ZOOM lens can go from wide angle distance
shot to telephoto close -up- smoothly, quickly,
automatically ... without loss of focus or change
of lens. With AUTO -ZOOM, one camera provides
the near -far coverage normally supplied by two
cameras with conventional lenses.
Coupled with the new high quality Vidicon
type cameras now coming on the market, the
AUTO -ZOOM greatly extends the usefulness of
low -cost industrial and bróadcast TV equipment.
The AUTO -ZOOM TV16 is a product of Perkin -
Elmer, world leader in optical and electronic
instrument research and development.

Wiring and Terminations
Interconnection of all equipment
located throughout the truck is accomplished
by wiring through ducts
installed underneath the floor. All
incoming and outgoing lines terminate
at panels located on the curb
side of the truck. There are two
such panels. One panel is located
directly in line with the camera
control racks. This panel provides
connections for the 2 camera inputs,
3 microphones, and one remote
audio input, one video input,
microwave control output, video
and audio outputs.
The power entrance panel located
more to the rear of the truck contains
4 ac output receptacles and
main input power connection. The
external source of power required
to operate the color mobile unit is
single phase, 220 v., 90 a.
Storage of the camera and power
cable is located externally in the
skirt line of the truck. There are
three compartments provided,
which are capable of carrying approximately
1500 ft. of camera
cable and 100 ft. of 4 conductor
No. 4 power cable. Each color
camera requires 3 interconnecting
cables, therefore, the 1500 ft. of
camera cable mentioned above actually
serves the requirement of 2
