Specification 11401
for a
Film Viewer, . Model 705v
1 June 2.962
1.0 SCOPE. This specification details requirements of the Model 705 V
ram Viewer.
2,0 APPLICABLE STANDARDS. The viewer, auxiliary equipment and support
equipment is built to best commercial standards. Due consideration has
been given to the requirement for operation and maintenance by semi-
skilled personnel.
310 YIEQVIREMENTS.
3.1 DESIGN REQUIREMENTS.
3.1.1 GENERAL com OURATION. The film viewer has the general arrange-
ment and layout shown on drawing 1,
a.
b.
Overall width does not exceed 34 1/2 inches to
facilitate movement through 36 inch office doors,
elevators, etc.
Projection of the image through a rotatable plate to
allow image rotation without using dove prisms, which
reduce resolution and introduce distortion.
c. The film transport handles 35mm thru 9 1/2" wide
film. Specifically 35mm, 70mm, 5"; 6.6", 8" and
9 1/2". Other sizes optional, as specified.
3.1.2 PROJECTED IMAGE.
341.2.1 RESOLUTION. The prime objective of this design was to produce a
practical film viewer having the ability to resolve 200 lines per milli-
meter or more. Minimum resolutions achieved are 40 lines per millimeter
at 5X, 90 lines per millimeter at 12X and 150 lines per millimeter at 30X.
3.1.2.2 RISTORTION. Distortion of images will not exceed 1/10th of one
percent when projecting a calibrated grid and measuring at the screen.
3.1.2.3 DA$XTIOia. Image positioning controls are provides which
allow the operator to bring any portion of the film frame into view on the
screen at 50X magnification. The lateral movement of the film stage shall
be accomplished by a motor driven ball screw and nut or similar high
,reliability mechanical device. It is also possible for the operator to
:rotate the film stage through afull 360 degrees. A handle or grasp point
shall be provided for the operator to accomplish the rotation*

3.1.3. PROJECTION SYSTEM
3.1.341 L/GRT_SOURCE. The light source should be of an intensity to provide
100 ft. lamberts, the requirement for best viewing conditions, measured at
the viewer's aide of the screen under the following conditiona:
(1) maximum image magnification, 50X in this case; and
(2) 1.0 density filter fining the film gate. The 100
ft lamberts is the ultimate objective at maximum
magnification but if not attainable the absolute lower
limit will be two (2) ft lamberts.
3.1.3.2 COMAITSER SYSTEM. The condenser lens system will consist of suf-
ficient glass elements to insure that the beam of light shall be free from
spreading dUe to spherical aberration which will in turn allow for maximum
amount Of light being taken up by the system consistent with the dimensionS
of the light source. The condenser lens Shall be adjustable in order to
concentrate more light into the film plane commensurate with change of
magnification.
3.1.3.3 COOLING SYSTEM. A system of cooling (fan, if adequate) will be
provided to remove heat generated by the light source. It is required
that the filtered air be exhausted after having passed by the light source,
which is last in the channel of air passage. An absolute minimum of
vibration will be affected by mounting the cooling device in a separate
cabinet if it is vibration producing. Film gate temperature will be no
more than 1400 F at the film plane with a piece of film with a fogged
density of 1.0 completely filling the entire film gate. Ambient room
temperature to be 80?F, or below.
3.1.3.4 FILM GATE, The film aperture measures 5 z 5 Inches and has a
glass platen to hold the film flat while viewing. The platen is designed
to accommodate 35mm Up to 9 1/2" film in standard thicknesses.
3.1.3.5 FOOTAGE COUNTER. A footage counter is provided. Footage indica-
tion is displayed in lower left hand corner of screen. Counter may be reset
by button on control panel.
3.1.3.6 PROJECTION LENSES.
3.1.3.6.1 LENS. Lenses used meet the requirements for resolution and
distortion called out in 3.1.2.1 and 3.1.2.2.
3.1.3.6.2 LENS MOUNT. An operator control is provided for interchanging
lenses to provide variable magnification. Lens selection is performed
electrically. Three magnifications, 5X, 12X and 30X are provided. One
spare lens position on the turret is provided, making a total of four
positions. Extreme care was used in design of the turret to minimize the
effect of vibration.

3.1.3.6.3 VCCUS CONTROL. The lenses are par-focussed S6 that when they
are interchanged, the image ia in focus. In addition) en operator control
is provided for vernier adjustment of focus,
3,1.3.7 RELAY MIRRORS, The mirrors used for reflecting the projected image
are a high quality aluminized front surface mirror protected by silicon
monoxide coating. The mirrors are of sufficient flatness and thickness to
meet the resolution and distortion requirements of paragraph 3.1.31 but in
to case are mirrors to be lets than 1/2 inch thick. Mirrors are mounted on
a three point suspension system for ease in alignment, Care was taken to
prevent a. loss, of image resolution due to vibration in the mirror system.
1:1
3.1.3.8 $ 11$4 The screen material is LOP-60 (LS 60-GPL) Polacoat.
Minimum screen size shall be 28 inches x 28 inches. The screen is not
cemented into a frame and may be easily removed from the front of the
machine.
3.1.4 r024 TRANSPORT SYSTEM.
3,144.1 PILM?SPOOLS. The viewer will handle rolls of 9 1/2" width film
up to 250 ft. long, (6 inch maximum reel diameter) and 5" wide film up to
500 ft. long (7 3/4" maximum reel diameter) and of 70mm and 35mm film up
to 1000 feet in length. (10 1/2" maximum reel diameter). The film trans-
port system allows for spools of any Standard site.
3.1.4.2 rim' SCAN MEP. Normal flOfilm movement in forward and reverse
is by capstan drive of the film with variable control of the capstan drive
motor. Film speed with capstan drive is variable from .1 to 5 inches per
second. Sufficient control of the flofilmnovement will be provided to
insure smooth film movement at all scan speeds.
3.1.4.3 REWIND ME:Mt Rewind'and fast forward drive is provided by the
film spool tonne motors and avertable contra. A maximum rewind speed
of 200 ft/min is provided. Sufficient contra of the breaking system is
maintained to insure there will be smooth stop motion when the variable
control is returned to the Stop potition.
3.1.4.4 PIM TRANSPORT CONTROLS. Film transport control logic than
Interlock the film transport operations to that it is virtually impossible
for an operator to damage film by improper sequencing of film transport
controls.
3.1.4.5 PERMANENT CIRCUIT DIAGRAMg. To mihfmize the effect of 100t in-
struction books) a circuit diagram of the transport control and lens
ahift control circuit is permanently glued tO the inside of one of the
cabinet covers.
3.1.5 OPERATING ENVIRONMENT,
3.1.5.1 ATMOSPRERE. The machine is designed for operation in normal air
conditioned office environment.

by function lona suitably identified. Operation of controls follows es-
tablished conventiens such as up for on, clockwise for increase, etc.
3.1.6.4 SAFETY. Projection and overhanging edges which could injure
operator or maintenance personnel have been reduced. All edges and
corners of the cabinet are rounded. Chassis and cabinet have A positive
connection to ground thru the AC line cord.
3.2 MATERIALS PARTS AND PROCESSES.
