DigiLens, of Sunnyvale, California, US, has developed a liquid crystal-based lens that provides customized diffraction gratings depending on which of its layers are 'switched on'. The application ...
US engineers have succeeded in creating a near-perfect ‘superlens’ that uses the principles of metamaterials to overcome conventional diffraction limits. The lenses could be used in ...
It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...
What is the Diffraction Limit? The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It ...
