a. Assemble the serrations of the Ektalite field lens (#3188l-P3) to the ground surface
3f the ground glass (#13017) and bind the two opposed 3-1/16" long edges together with
papel' tape (#11504).
(i) Position the-asserr,bly with tape to the outside edges and the polished side of the
ground glass to the top.
(2) Bend the frame ears inward enough to hold the assembly. Do not attempt to bend
the ears down--it will crack the glass.

assem`ole two #1 x i/4-" long round head sol.ews (#15181-4) at the back, and two special
machine screws (#118) at the front:
g. F.ocus as follows:
(i) Set lens wide open. Set camera f.ilm plane pal.allel and about 6 feet from a 4 foot
square target. Use pie charts ol. similar, or old calendar sheets having large and
small figures.
(2) Using a GRfiFLLX focusing panel, focus on film plane. Ijower mirror and adjust top
ground glass--check each corner and center.
(3) Check infinity focus using pro6edure of step (2). Tighten scl'ews when general
focus is satisfactol'y.
