Abstract [en]

Human today stress more and more importance on their health due to social welfare and advanced medical equipment. Ophthalmological device design already creates healthy living patterns around it. In the design process, effect quality of design and cost manufacturing is the objects which is necessary to be considered. The project itself was commissioned by the well-known Eye-care clinic [confidential] in High-end market.

Therefore, a low-cost multi-functional fundus camera medical system, called the Retina Microscope is under developing. The whole process of the optimization of a Retina Microscope and designing aspherical lens instead of the old model will be described. The purpose is to be able to inspect the eye (the inside retina and outside cornea) and prevent needless blindness. Using a low-cost LED-based point illumination and a ring-light solution provides more flexibility for integrating refractometry. By using Zemax is to optimize the solution for the integration of a non-mydriatic fundus camera and a cornea camera.

Two prototypes are already built, which are under testing and optimizing. Design and optimization is run by optical design software ZEMAX. The simulation analysis, setting parameters, the results of comparison and the controlling of optimization programming is the core of the design. My final design about plastic aspherical doublet lens is adopted by the company, and began to manufacture commercially.
