New work enables optical microscopes to measure these nanometer-scale details with a new level of accuracy. Over the last two decades, scientists have discovered that the optical microscope can be ...

Figure 1: Basic compound microscope: Light from a source is focused onto the sample (object) using a mirror and condenser lens. Light from the sample is collected by an objective, forming an ...

Light microscopy is used to make small structures and samples visible by providing a magnified image of how they interact with visible light, e.g., their absorption, reflection and scattering. This is ...
