Abstract: Described herein are systems and methods for reducing image aberrations in high magnification photography with partial reflectors. In particular, by an imaging device or camera that is built into or is included in a cell phone, smart phone, tablet, laptop or any other mobile device. The systems and methods include a light passing through a lens, a portion of said light then undergoes a number of partial reflections in-between two partial reflectors, and a portion of said light then reaches an imaging sensor. The partial reflections enable a longer light path to reach the imaging sensor, thus enabling a longer focal length to be used, which enables higher magnification. Described are methods and embodiments to select the physical parameters of optical elements in systems with partial reflectors, in order to create images with reduced image aberrations.
