Millisecond Camera
|
|
 |
The
camera is shown mounted on a Worrell head with a Nikon ED 50-300
zoom lens. The overall diameter of the camera is 81 cm (32 inches).
Behind
the black faceplate are the relay optics and rotating mirror that
relay the image to the film. The round black cover just above the
viewer assembly is the port for the film cassette.
The
camera accepts Arri PL, Panavision PV or Nikon lenses. The viewer
system has a 10% pellicle viewer and a TTL video tap for simultaneous
video recording.
Complete
specifications are listed in the specifications
page.

Camera Controller
|
|
 |
The
controller manages the speed of the camera, the timing triggers
for taking a shot and the vacuum pump power.
You
use the controller to set your desired speed which can be anywhere
from 120 to 12,000 frames per second. The controller will ramp the
camera up to speed and hold it to accuracy within 12 fps.
|
Light Source
|
|
 |
This
is the flash system used for shooting at the fastest speeds. The
system generates an extremely bright square pulse light which can
be set to last exactly one revolution of the drum. (It does not
pulse for each frame.)
It
has one flood light head and one spot light head. It can drive one
or both of the heads, though the total amount of light energy produced
is the same either way.
|
Timing Package
|
Top of Page |
 |
The
timing package is used to synchronize the camera system with events.
It includes laser triggers, sonic triggers, electronic triggers
and a manual trigger.
The
package also includes a proportional time delay generator for more
complex set-ups, and a digital oscilloscope to test and monitor
timing signals.
The
timing package is not always required. It depends on what you are
wanting to capture.

Film Loader
|
|
 |
The
film loader takes a 100 or 400 foot roll of film and measures off
the proper length of film for a shot, which is about 228 cm (90
inches).
The
film loader puts film into the cassette, which then loads the film
into the camera. Loading can be done in daylight conditions.

Cassette in
Loader

 |
This
is the film Cassette after a strip of film has been measured, loaded
and cut from the Cassette Loader.
You
load unexposed film from the loader into the cassette. You then
use the cassette to load film into the camera.
|
Film Cassette
|
|
 |
The
cassette loads the strip of film into the camera, and recovers the
film after a shot. It stays in the camera during a shot.
The
cassette is open to show the film inside, but of course you would
never do this during operation since it exposes the film.

Cassette in
Camera
|
Top of Page |
 |
The
film cassette loads film into the camera. The cassette is inserted,
rotated one click, and then opened. The cassette cannot be removed
by accident while open. Then the cassette is rotated again one click,
which engages the cassette's rollers against the drum of the camera.
The
crank on the cassette turns the rollers, which turns the drum as
the film loads into the film track of the drum. The cassette is
then moved away from the drum to take the shot. The process is reversed
to recover the film.

Film in Camera

This
image shows the strip of film loaded into the drum of the camera,
sitting end to end.
The
cassette has been removed to show this, which of course you would
never do during actual operation since it exposes the film.
