OPERATION OF OPTICAL SYSTEM
THE IRIS CONTROL is the front lever which projects through the top of the optical
system housing. When this lever is to the left (as viewed from the rear of the unit), the largest aperture
is provided. Smaller apertures are obtained as the lever is moved to the right.
THE SPOT SIZE CONTROL HANDLE is located on the right hand side of the opti-
cal system just above the base rail. A variation of spot sizes from full flood to small spot can be
obtained by moving the spot size control handle from one extreme to the other. Beam intensity is
increased by this optical system when reducing from flood to spot, and maximum intensity is reached
when the spot size control handle is in the extreme forward position.
THE MAXIMUM FLOOD SPOT is obtained with the iris control lever to the left
(away from operating side) for the largest aperture and with the spot size control handle moved as far
to the rear as possible.
SMALLER SIZED SPOTS are projected as the spot size control handle is moved
forward. Most of the spot sizes needed will be produced with the iris in its maximum open position.
FOR A “HEAD SPOT,” or any spot smaller than can be obtained with the spot size
control handle in its extreme forward position, shift the iris control lever to the right (toward operating
side) for a smaller aperture. The iris control lever should always be returned to its extreme left
position before the spot size control handle is again moved to obtain larger spots.
THE MASKING SHUTTER (chopper) lever is the middle lever projecting through
the top of the optical system housing. The masking shutter blades are operated by this lever to shape
the projected spot to a rectangle, strip spot, or dousing.
THE DISENGAGED POSITION of the masking shutter lever is to the extreme right
(toward operating side) and varying degrees of masking to complete cutoff are obtained by moving
the lever to the left (away from operating side).
THE ANGLE of the masking shutter blades can be adjusted to compensate for the
horizontal projection angle. Remove the color boomerang and optical system housing, and loosen the
screws holding each of the masking shutter blades enough to allow movement. Ignite the bulb and
adjust the angle of the bottom blade by tapping with a screwdriver so its projected edge lies parallel to
the footlights. Tighten the screw. Operate the masking shutter lever to close the blades. Adjust the
upper blade to close in line with the bottom blade and tighten the screw.
THE FADEOUT MECHANISM AND DOUSER CONTROL is the rear lever pro-
jecting through the top of the optical system cover. This lever controls the intensity of light from
complete fadeout when the lever is to the left, to full intensity when the lever is to the right.
