Abstract
The ultimate goal of optical instrumentation is to achieve the desired image quality in a given application. This requires a homogenous blend of optical and mechanical design, fabrication, system integration and testing tasks. The space optical systems generally require near theoretical performances in hostile environments within size, weight and cost constraints. Hence a careful tolerance analysis plays a crucial role in these systems. For space optics, the importance of image quality, cost and related tolerance analysis cannot be over-emphasized. In this paper, we have tried to address the challenge of achieving an optimum image quality through a cost effective tolerance analysis. Two different space optical systems are considered: the UV imager for the International Solar Terrestrial Physics (ISTP) Mission and an afocal telescope for the Advanced Polarized IR Imaging Sensor (APIRIS). These systems are described along with their required performances and designs, with an explanation of the tolerance study conducted. The effect of tolerances on the image quality and cost are investigated.
