本文讨论了CANARY主办的高阶自适应光学升级项目（CHOUGH）中直径为50 mm的大气色散校正器（ADC）的设计。通常为了避免光瞳致动器-小透镜阵列失配，ADC通常放置在非常靠近光瞳平面的位置。由于CHOUGH光中继器的限制，本设计的目的是实现一个非光瞳共轭的ADC，适合于位于准直光路内的任何位置。ADC还需要满足非常小的瞳孔位移要求，以确保瞳孔稳定性。ADC是Amici棱镜型，由两块胶合双棱镜板组成。两个板反向旋转，以校正不同的天顶角，从天顶角到60°。
We discuss the design of a 50mm diameter Atmospheric Dispersion Corrector (ADC) for The CANARY-Hosted Upgrade for High-Order Adaptive Optics (CHOUGH). Usually to avoid pupil actuator-lenslet array mismatch, the ADC is Customarily placed very close to the pupil plane. This design aims to achieve a non-pupil conjugated ADC suitable to be located in any place inside the collimated beam path, this is due to the restrictions given by CHOUGH optical relay. The ADC also needs to satisfy the very small pupil shift requirement, for pupil stability. The ADC is of the Amici prism type, made up of two plates of cemented double prisms. The two plates counter rotate correcting for the different Zenith angles, from the Zenith up to 60°.
