An improved conical panoramic mirror element design is disclosed such that the panoramic vertical field of view is not fixed and the image covers at least 90% of the toroidal image pixels of an imaging device. The data required to prescribe the panoramic conical element includes the position of the detector device, the most negative vertical scene angle, the most positive vertical scene angle, the panoramic cone's base diameter, the cone's apex to base ratio. These are utilized according to a mathematical prescription that optimizes the mirror element's design.
