Design of a Cell Phone Lens-Based Miniature Microscope with Configurable Magnification Ratio

Application of cell-phone-based microscopes has been hindered by limitations such as inferior image quality, fixed magnification and inconvenient operation. In this paper, we propose a reverse cell phone lens-based miniature microscope with configurable ratio. By switching the objectives three camera lens applying digital zooming function phone, is built continuously ratio between 0.8×–11.5×. At same time, can capture high-quality microscopic images maximum resolution up to 575 lp/mm field view (FOV) 7213 × 5443 μm. Furthermore, moving tube module out body, compact <20 mm side length cube, improving operational experience profoundly. The proposed scheme marks big step forward in terms imaging performance user convenience for microscopes.
