Paper Abstract

KAOS (Kilo-Aperture Optical Spectrograph) is a multi object spectrograph fiber fed from the f/1.7 prime focus of Gemini north telescope. A wide field corrector has been designed for the focus to provide a sub arc-second image over 1.5° FOV. The corrector includes four lenses and ADC (atmospheric dispersion compensator) prisms, which also act as an imager stabilizer. This paper describes the corrector design and presents the optical performance. In the final section, some other design options are discussed.
