In this paper, in order to separate images in four spectral bands (from blue to near infrared) in multispectral cameras, four-color separation prism advantagesarereviewed. Then, while description of ray tracing of four-color separation prism, main design parameters and principlesarementioned.After that, design of a four-color separation prism model that attached to detector (CCD) by using the Zemaxsoftwarearedescribed,also spot diagrams,ray tracingand aberration graphsare analyzed. Finally, while expression four-color separation prism characteristics that yield fromprogramming with Zemax software, including weight, length of the optical path and thickness of equivalent blade, itsspecifications in remote sensing satellite multispectral camerasareexplained
