Research output: Chapter in Book/Report/Conference proceedingConference contribution


We developed Korsch type telescope for the compact advanced satellite payload. The optical system has a diameter of 600 mm with F/11. All mirror component was developed to have better performance than the tolerance allocations. The alignment of three mirrors are guided using the algorithm, merit function regression method. During this process we found a new approach for the far field focus optimization. To minimize aberration, we have been focused on the main Zernike term (astigmatism and coma), but the focal plane position is also important to proceed to the next step. We will present our optimization process, and the result of performance.
