Wide-angle pupil relay for mobile phone-based fundus camera

摘要

The optical imaging system is a first lens system housed in a main body of a mobile communication device, and the first lens system is a space in a first optical axis and a reference plane associated with the main body. A first lens system having a first entrance pupil fixed therein and a first focal length, and an optical telescope providing diffraction limited imaging within a spectral range of at least 486 nm to at least 656 nm The optical imaging system includes the EPE when the optical telescope is inserted between the first lens system and an entrance pupil (EPE) of an eye vision system. An image is formed at substantially the same magnification on the upper side and vice versa.
