Error Budget Analysis of FIMS Optical System
Abstract
Far-ultraviolet IMaging Spectrograph (FIMS) is under development as the main payload of the first Korean science satellite, KAISTSAT-4. An extensive sensitivity and error budget analyses of FIMS optical system have been performed. As an way of estimating aggregate effects of all tolerances, a Monte Carlo simulation is used. The simulation result shows that the optical performance required from the science objectives is achieved within the probability higher than 99.9%.
