The spatial resolution of any conventional optical microscope is limited by the diffraction of light waves on the objective aperture, with white light the best optical microscopes resolution is about 200 nm. One way to overcome this limitation is microlens microscopy. Microsphere microscopy is a type of label-free microscopy in which spherical microlenses are placed directly on or near the sample to produce high-resolution optical images. With label-free and real-time imaging, optical microlens microscopy shows great potential in medicine and biology.
