1. This memorandum documents Part 1 of the In-Plant Acceptance Tests
of the High Precision Stereocomparator. The tests were performed from
1600 on 17 November to 2030 on 19 November.
2. The data taken is listed in this memorandum in tabular form where
applicable. In other cases, narrative explanations of procedure are pro-
vided. Reference is made on each test to the appropriate section in the
referenced Acceptance Test Plan.

procedure. Part 1.
A.1. thru A.8. These tests assured that the panel meters responded
to observed changes in optical elements. The thrust of the test was not
to check calibration of the meters, but to assure that they followed the
movements of the elements. A.6. was not checked off because a minor
glass element had been broken and not yet replaced. The remaining tests
were satisfactory.
A.9. and A.10. These tests checked 7 working parts of the system
1) joystick movement, 2) trackball movement, 3) anamorph ratios, !E) objec-
tive lens interchangability, 5) zoom magnification, 6) Binocular mono
switching capability, and 7) focusing capability. It also showed an
inaccuracy in the calibration of the rotation panel gauges. The left gauge
was off by 60?. Other than that, the tests were satisfactory.
A.11. thru A.A. These tests checked the controllability of the
platen illumination system. These tests were satisfactory.
B. This section was to show that the gauge and flow meters on the air
system were working properly and set correctly. The procedure pointed out
the need to assign a nominal value plus a tolerance for variability in a
dynamic machine condition.
Item B.I. was not set at the nominal value because it was using
machine-shop air. When a single-purpose compressor is used, as it will
be in the operational system, these listed values can be attained. ;' CiQt~t

except that the "Trackball Coarse" button was depressed as opposed to
"Trackball Fine" in the previous test. Also, it is necessary to use the

F.1 The difference in 3.0 & 3.1 density was quite apparent when one
looked at the field of view.
F.2 The color filter does move in and out of the optics train on both
sides. No measurement has been made at this time of its transmission
characteristics.
F.3 The image wander was not checked during this series of tests. An
attempt to measure the backlash of the objective focusing system was made,
but failed due to the lack of a smooth surface on the objective torrent
on which to indicate.
F.4 The EDL anamorphic target was measured with a fixed eyepiece
reticle in order to determine the anamorphic setting. It was determined
that the anamorphic correction was operating within 1%.
The distance measured at 1:1.0 anamorph setting was 11.5 At
1:1.5, the distance read was 1.1.7 At 1:2.0, the distance read. was 11.55.
Therefore, the actual anamorph connection @ 1:1.5 was off by 0.2, or 1.7%.

F.5 The zoom ran{-0 was measured by reading the distance on a scale
between fixed. lines in an eyepiece reticle.
On the left side, the distance between the fixed lines was
mea ured to be 9.75 @ lOx. At 1-00x, the distance was read to be 97.5?
The ratio, then, was 97.5 or 1.01.
9.75
The right side read 9.8 @ lOx and 98.6 at lOOx. The ratio was
98.6 or 101.
