Figure 1: Exploded view of the D-Eye module (angles and distances between components are approximated). Retinal images are acquired using coaxial illumination and imaging paths thanks to a beam splitter (C). The blue arrow depicts the path of the light; red arrow depicts the path of fundus imaging. Device components are glass platelet (A) with imprinted negative lens (), photo-absorbing wall (B), beam splitter (C), mirror (D), plastic case (E), diaphragm (F), polarized filters (G, H), flash and camera glass (J, I), and magnetic external ring (K).
