Head-mounted microscope design (IMAGE) Optica Caption A schematic of the components of standard head-mounted microscopes (a) and the new design (b-c), which eliminates the standard illumination optics resulting in a device that is significantly more compact and lightweight. Panel (d) shows that the microscope retains high resolution, with the ability to distinguish lines just over 4 μm wide. Credit Joseph R.
