摘要：

The James Webb Space Telescope (JWST) is a large space based astronomical telescope that will operate at cryogenic temperatures, and utilizes a segmented primary mirror with active control. To achieve the science goals for JWST, the image quality over a wide spectral range is necessary. Several metrics related to the quality of the PSF have been used to capture the optical requirement to meet the science goals. We will present the requirements allocation from Point Spread Function Metrics to spatial frequency content in Wave Front Error allocations that reflect the unique forms associated with the active control aspects of the design.
