The Imaka project is a ground layer adaptive optics system proposed for the Canada-France-Hawaii Telescope. This paper presents the optical design of a Cassegrain mounted ground layer adaptive optics system with a 0.8 degree field of view for Imaka. The design incorporates a Takeshi concentric ADC and a f/8 to f/5.7 reducer. This is followed with a novel double pass system to image the pupil on a 300mm mildly concave deformable mirror and re-image the system on the detector. The design meets the required 0.15" 80% encircled energy image performance, including correction for atmospheric dispersion. The optical design is presented with the predicted imaging performance.
