An instrument is described that provides a stable magnified image for ophthalmoscopy and a low power operating microscope combined to allow greatly improved fundal inspection and to eliminate the need to change instruments during detachment surgery.

The Scanning Probe Microscopes (SPMs) based lithographic techniques have been demonstrated as an extremely capable patterning tool. Manipulating surfaces, creating atomic assembly, fabricating chemical patterns, imaging topography and characterizing various mechanical properties of materials in nanometer regime are enabled by this technique. In this paper, a qualified overview of diverse lithog...
