ASPHERIC OPTICAL ELEMENTS PROGRAM.
Abstract
Work was done concerning problems arising in the electronic control system of the machine, and in the temperature control system of the room in which the machine was located. The control system for the Y axis stepping motor was found to be unreliable and steps were taken to correct this situation. The temperature control system did not prove adequate to stabilize the room temperature, and the variations that were encountered in the machine behaviour because of this were beyond tolerable limits. It appears that the room temperature control was established and that variations fall within a total 1-degree range. A design of a 24 in. f/4.0 lens was undertaken as an alternate to the 48 in. f/4.0 lens. (Author)
