Title: Widestock exposure modification
Author: Roberts, Kurt D.
Abstract: A system exists for the exposure of large pieces of sensitized material. The strips are exposed, processed, and viewed by transmitted light. This procedure is used to gauge the quality of the film coating process. There are three problems with the existing system: uneven illumination, the timers do not take into account light decay, and finally, the operators, on occasion, set up the wrong conditions for an exposure. The purpose of this thesis is to modify an existing process for the automated exposure of wide stock strips. These modifications are to replace the system's components with state of the art, commercially available equipment. The equipment was modified to perform the desired output as necessary. The equipment is then to be interfaced with a suitable computer and software generated to automate the system. Existing lights and timing circuits have been replaced with lighting arrangements that approximate actual end use of the products tested. Exposure control is provided by an "off the shelf" light integrator. An existing computer, (DEC 11/34), adapted for automation purposes was then interfaced with the new equipment to operate the system. Software is planned which will take over partial responsibility for operating the system.
