dvanced Tilt Top Light Tables
1. In the letter part of 1963 various individuals of your orgari-
sation were given the opportunity to make suggestions for the improvement
of this 9" x 16' Tilt Top Light Tables,
2. As a result of these disscuaeione the ttached Development
Objectives gxtitled, "An Advanced Tilt Top Light Table," dated
29 January 1964, were formulated. This document 4as submitted to
industry and after a competitive evaluation of the resulting proposals
was made it was decided to initiate a parallel effort for this
development. Frm the start it was recognized that of the two
contractors selected had the higher probability of
success-. nevertheless, cause sa a importance of this effort
I I was selected as an alternate or ''back-up, supplier.
3. After two and a half yearn of intense monitoring by thi
office and extensive inputs from your organisation, the ligh=t tables
have been delivered. All of the requirements of the Development
Objectives have been more or less satisfied; but, as a consequence,
the light tables ha a become relatively complicated in com rtson to
existing equipment. These units can therefore serve .s 'test bed"
to determine if all or part of the advanced features should be in-
corporated into a production version of an advanced light table; e.g.,
the better features of each light table can be combined into a
single production version and the unde t ~ able features eliminated
thereby reducing loth *omplexity and cost.
l+, Altho%:~i most of the advanced features are direct and
.ght-forward solutions, some deserve discussion.
