1. INTRODUCTION. These development objectives describe the require-
ments to be met in the design and fabrication of a prototype Anamorphic
System for the High Power Stereoviewer (Twin Dynazoom).
2. CONCEPT. This development will produce an anamorphic system that
can quickly and simply be attached to and removed from the High
Power Stereoviewer. Although the existing instrument has found
general operator acceptance, an independent anamorphic magnification
capability is required for each optical path. This anamorphic system
must not significantly reduce the optical performance of the basic
stereoviewer, but must be simple to operate and be reproducible in
production quantities at a realistic price.
3.1. Evaluation and selection of the successful proposal will
be based on cost, indications of the contractor's commitment to fulfill
these objectives, and the experience and ability indicated by the
inclusion of relevant specifics.
3.2. Proposals should discuss problem areas and schedule major
steps in the production process.
3.3. The program will be divided into two phases: Phase I will
be the Design Study and Phase II will be the Fabrication Phase.
Initiation of Phase II will be predicted upon the successful completion
of the design study.
)4 GENERAL DESCRIPTION. Thel High Power Stereoviewer
is used in conjunction with the objective
lenses and compensating eyepieces. The objective magnifications are
3X, 6X, and lOX and the compensating eyepiece magnifications are 6X
and lOX. In addition, a .3X objective is being used.
This development will add an additional magnification range to one
axis of the optical field.
5.1. Existing Instrument. The basic High Power Stereoviewer is
described rn publication Number 53-335; however, a
significant improvement in the optical performance has been achieved
utilizing the above mentionedl -1 objective lenses and com-
pensating eyepieces. The anamorphic system must not significantly
degrade the optical performance of this combination.

5.2. Optical.
. 5.2.1. Anamorphic Range. The system shall have a
continuously variable anamorphic magnification from 1X to
2.2.X; i.e., the anamorphic ratio (ratio of the magnification of
two perpendicular meridians of the optical field) shall be from
1:1 to 1:2.2.
5.2.2. Field. The maximum loss of field must not exceed
5% of the normal instrument's total field. The optical field
must be as flat as the field of the instrument without the
addition of the anamorphic system.
5.2.3. Anamorphic Axis Orientation. The direction of the
anamorphic magnification (anamorphic axis) shall be rotatable
through 360?.
5.3. Physical Configuration. The anamorphic system must be as
compact as possible and must incorporate superior human engineering
features. Simplicity of design and operation is of upmost importance.
Specifically, the eyepoint shall not be extended more than three
inches from the position of the present eyepoint and an operator
wearing glasses must be able to operate the instrument. An estimate
of the size and weight of the contemplated system must be given in
the proposal and an artist's concept must be included.
5.-i-. Interchangeability. The system must be configured to allow
disassembly of the anamorphic system from the stereoviewer within five
minutes without the use of special tools. Accommodation must be
made for utilizing the system on any =High Power Stereoviewer.
5.5. Costs. The proposal must include the cost of producing
one prototype and an estimate of the costs of building 5, 10, 20, and
30 units.
5.6. Drawings. Design and fabrication drawings are required.
5.7. Operator's Manual. A comprehensive operator's manual must
be included with the prototype and must be in a form which can be
easily updated for the production model.
5.8. Government-Furnished Equipment. The successful contractor
will be furnished one High Power Stereoviewer as Government Furnished
Equipment.
