Light field microscopy: principles and applications

WebBrightfield microscopy is the most elementary form of microscope illumination techniques and is generally used with compound microscopes. The name "brightfield" is derived from the fact that the specimen is dark and contrasted by the surrounding bright viewing field. Simple light microscopes are sometimes referred to as brightfield microscopes. WebLight Microscopy •Light microscopy refers to the use of any kind of microscope that uses visible light to observe specimens. •Types of light microscopes are: 1. Bright-field, 2. Dark-field, 3.
