Differential interference contrast microscopy

WebJun 6, 2011 · DIC microscopy is a technique which uses gradients in the optical path length and phase shifts to make phase objects visible under the light microscope. In this way it is possible to observe living cells and organisms with adequate contrast and resolution. Images produced by a DIC microscope are relief-like and seem to have a shadow cast. WebMicroscopes are a microbiologists main tool to visualize the world that can not be seen with the naked eye. Microscopes allow for Magnification (the ability to make objects appear larger by bending light) and Resolution (the ability to show detail or to identify that 2 adjacent objects are separate objects as opposed to a blurry blob).
