The optical design is introduced for the optical-infrared camera, CASCAM, developed by Purple Mountain Observatory. CASCAM employs an infrared array HAWAII-1 and a CCD, simultaneously covering the wavelengths of 0.4---2.5?m, and is designed to make imaging and polarimetric imaging with the 2.16m and 1.26m telescopes at Xinglong station. The camera optics consists of a focal reducer and the Offner reflection system; the results of optimization with ZEMAX software show that the design can satisfy the proposed observational requirement. The camera design is implemented by the achromatic focal reducer well-designed for very wide wavelength band from optical to the near-infrared, and make some new attempts with wedged dichroic beam splitter non-refrigerated optical-filter wheels and refraction dithering system.
