Investigation of the use of an electronic sensor in a superwide field camera
Abstract
The suitability of the Reticon RA 100 x 100 matrix detector for a superwide field camera was investigated. An optical model of this camera for checking the characteristics of Reticon and camera were developed. The production of the strongly aspherical hyperbolic mirror for the superwide field camera was difficult. The use of a numerically controlled milling machine for the production of the grinding template used to generate the desired mirror surface led to large improvements. The Reticon RA 100 x 100 was tested in the laboratory as well as on the telescope. Its use in astronomical areas is out of the question, as the high color temperatures that occur reduce the effective sensitivity too greatly.
