work was aecoili.hed on the contract in the report
The mechanical design and details for the two rail vertical supp
structure were oompIeted Optical design for the elimination of
the illumination under-filling condition evidenced in the bread-
board setup and previous optical calculation was continued.
The cqr4enser system has to cover a range of approximately eight
inch**, the magnification rage from four thru twelve inch lenses.
A comprehencive ray tracing of various systems disclosed that to
Y fill all apertures in the range, a system involving
riser and lens arrangements differing from those described to
eustomer representative at the A. S. P. Convention on March 18,
4 in Washin on, D. C. was required.
naer system for the 105 and 180 mm (4" and 7') 1 ns
Y described and as shewn in Figure 1. The adjustment
tion will be necessary when changing from the 4 to the
h lens. Note also that the uppermost "A" condenser is in axial
poslti.on in combination with two lower condensers. For adequate
filling of apertures for the magatUattons to be covered by the
12" lens the uppermost condenser is to be removed and the lowest
condenser exchanged for a condenser contributing less power to the
system. PUrthermore a 12Y lens of larger aperture IS required.
A number 0$ stook S&L 12" lenses were tested for resolution distortion
and proper filling in the breadboard system from which a 300mm r/
T;*t tecsar type was selected. This optical system will provide
a complete filling of the screen images at all magnftebation with
the precribed focusing of the lamp and inter changes of condensers
as described and illustrated. Mechanical design and detail drawings
for the enalrger head and slide have been delayed pending the final
specification of the condenser-lamp systems required. With the
co lotion of the optical design mechanical design will proceed.
To date only Preliminary investigation into the mechanical detign,
-40man factors., and operational considerations of the enlarger head
has been PoSsible. The most prom! arraagements of components

o comply with the operational Thnotions required, be least obtrusive
to the operator, and to be balanced in all condenser positions is
shown in figural. A rotary condenser turret pivoted centrally
aft of the projection axis would carry the two lower condensers.
The center condenser is mounted in a fixedmosition on axis and
the upper condenser is a slide such that it will be retracted rear-
ward as the lower turret is rotated 1800 to align proper condensers
when ;hanging from the 4"-7" lens system to the 12" lens system.
To? reduce the number of manipulations required by the operator the
upper condenser may be linked to the lower turret rotation such
that rotation of the turret by the operator shall have retracted or
inserted the upper condenser as required. He shall in addition be
required to index the lamp position and proper projection lens to
complete the. changeover.
To insure that the film position shall not have been distrubed
during interchanges of the lower condenser, a single glass sand-
wich platen remains in projection position holding the film in place.
Similarly a stream of forced air 90 being continously directed
across the platens upper surface and rearward away from the opera-
tor to maintain suitable gate te eratures. The replacement of
the 12" 016 lens with a 12" 04 5 will require modification of
the existing turret assembly.
