1. The original contract called for 6 each 2X4printers
and 6 each 2-Stage rectifiers and a total amount of
a. recognized on 9 February 1959
that an overrun would be forthcoming;at this time 23% of
the contract funds had been expended.
b. On 6 May 1959 wrote to TSS 25X1A
that an increase of total costs to was necessary25XlA
and gave the reasons (see Page 3, Appendix A) .

c. On 16 June -L9-6,(Y received a 25X1A
letter from acknowledging t e May 6th increase
and telling them to wait until they had spent 85% of the
money.
d. On 1 September 1959 stated t(25X1A
the customer that additional overrun had been experienced
now estimated to be 25X1A
25X1A
e. On 31 December 1959 (see Appendix B) 1A
-stated to attention that J~C1A
total cost for 6 systems now estimated at 25X1A
25X1A
f. On 11 January 1960 (see Appendix C) -
a letter giving cost breakdown and
25X1A
g. On 20 January 1960 (see Appendix D) X1A
stated in a letter to that was 25X1A
necessary for 6 each systems and that this is the total cost
including fixed fee or that 2 each systems could be furnished
at original.Fontract price.

It is interesting to note that these original prices are based
on 1957 base manufacturing overhead of 193% and engineering overhead

of 91%. Today these overheads are: manufacturing 202.95%
and engineering 100%. I was assured that these w erheads are
used for all contracts, civilian or government.
h. On 2 March 1960 (see Appendix E) a letter
was sent to the government stating that
would furnish one complete additional system at a fixed
price of This offer holds for 60 days and is
for one additional system only; any other additional systems
would have to be arbitrated for.
2. Appendix F is a complete set of progress reports
25X1A from on this system.

TESTS
a. Appendix g shows the result of tests using
the 2X reduction printer made on various films.
113 1/mm is the best resolution obtained on axis.
stated that the focal length was designed
to keep the field angle small and that any other lens of
this focal length and f stop would perform within 10%
of this lens. The present lens is diffraction limited to
200 1/mm on axis. The lens is performing at less than
this in order to give a flattening of the curve, thus
rising the resolution on the edges over what it would
be if 200 was achieved at the center.
b. Since this was an R & D cost, plus fixed
fee contract, the manufacturer tried two light sources
before determining that present, third source,.wh#ch is
a germicidal, fluorescent light which emits light of the
proper spectral characteristics. A diffraction filter
had to be used even with this light source in order to
make the lens perform. This filter had to be cemented
between lens elements B & C since the filter deteriorates
rapidly when exposed to air. In addition both D surfaces
were given an aspheric coating. Some one of the project
monitors approved this action. In addition, some one
approved of the focal length and f stop of the present lens.
c. The 2X reduction printer could be made to
perform better by opening the f stop. This would mean
a new lens and more time and more money. An f/4 system
should deliver about 200 lines over the entire field and an
f/2 lens would deliver about 400 lines.
d. Appendix H is the results of tests ran at
on SO 278 on 2 and 3 March 1960. This
film peaks at a lower portion of the spectrum than the
lens peaks at. Further tests will be run using different
spacings of the lens.

2. Two-stage Rectifier--
a. The lenses of the 2-stage rectifier are
presently giving 30 1/mm on axis and 8 1/mm at the
corners; however, this system is not ready for
testing due to vibration experienced from the traveling
light source. The traveling light source also is giving
banding. ori't'lre finished print. This is expected to be
smoothed out by causing the IBM card system to give
a smooth transition from area to area rather than the
stop and start movement presently achieved.

RECOMMENDATIONS
1. a. That film and/or paper stock to be used on the
2-stage rectifier be purchased in roll form in 22 and 32
- ~. inch widths. (Easel sizes are 22" x 43" and 32"
x
64")
.
thus solving the masking and part of the vs, cu ..rob l-e.i .
The entire easel could then be covered with the stock,
b. That each easel be provided with a rail on the
supporting the weight of the film and thus removing one
of the force vectors that now pull the stock from the vacuum.
c. That each easel be provided with a simple clamp
on the top front which will hold the film flat stopping the
tendency to curl.
d. That each easel be provided with a simple cassette 17
mounted near the pivot to hold the raw stock and that each
,,0
cassette contain a plate at the bottom with smooth bearings
to allow easy feed out of raw stock. 'd
0' ')
C
The above recommendations are easily accomplished Cith
no waste of time and no modifications other than the aforementioned
additions.
This will reduce to one man the operation of placing the raw
stock in position.
Completely covering the easel saves time in masking and
determining position of masks.
Savings in time and savings in carrying many sizes of stock 7
should outweigh the cost of raw stock.
2. It is recommended that it be determined how many
additional systems are needed and that they be ordered at a fixed price
as soon as possible. N

3. It is recommended that the new Reprogen lenses be d
supplied to if possible for mounting into the 2-stage 4
rectifiers, thus saving the cost of mounting and also saving the
cost of mounting the lenses.
4. That a contract be let for an improved resolution
either f/4 or f/2 lens to be mounted in the 2X reduction printer,
if this printer is to be used with high-quality material.

5. It is recommended that steps be taken to provide the
proper power for these instruments. The 2-stage rectifier requires
inter requires 1 amp/110 volts.
40 amps /220 volts, and the reduction _1
6. That representative samples of original negatives of various
tilt angles be provided to as soon as possible in o2d.XfA
that they may determine the IBM card deck that controls the light on
the 2-stage rectifier. 4 QiG 6 pF
