Microscopes are a staple of medical offices, laboratories and science classrooms everywhere. There are several different kinds of microscopes, but the most common type in use is the bright light microscope. It is also known as a bright field microscope. The bright field microscope, despite being ...

A bright-field light source for a surgery microscope emits visible light, the spectral intensity at the wavelength (672 nm) of fluorescence emitted from an observation object, is weaker than that in the other wavelength regions of visible light. As a result of the bright-field light source, ...
In this work, we present direct measurements of the phase point- and line-spread functions of a high-aperture microscope operating in transmitted bright field. Polystyrene nanoparticles and microtubules (biological polymer filaments) serve as the pure phase point and line objects, respectively, that ...
