Mobile device-based digital microscopy for education, healthcare, and agriculture

This paper shows for the first time how a mobile device such as a smart cell phone and a tablet can be used to realize such a highly-sought-after high-resolution digital microscope. Demonstration based on a low-cost molded plastic convex lens combined with our design packaging style shows that a portable digital microscope can be easily implemented featuring a measured high image resolution of >; 4.40 μm and a measured field of view of 5×5 mm
