Abstract

High Contrast Imaging using coronographic spots and pupil apodization masks is specified as an option for FRIDA. Studies have been carried out to determine the possible stops and masks options on the optical design for these purposes and presented in GTC III and elsewhere. In this work we present the influence of residual optical aberrations at different spatial frequencies on the FRIDA performance for High Contrast Imaging. These aberration figures were taken in account for the specification of crucial FRIDA optical components.
