Köhler illumination - Wikipedia

WebKöhler illumination is a method of specimen illumination used for transmitted and reflected light (trans- and epi-illuminated) optical microscopy. Köhler illumination acts to generate an even illumination of the sample and ensures that an image of the illumination source (for example a halogen lamp filament) is not visible in the resulting image. WebFigure 1(a) shows the ray paths for illuminating light produce a focused image of the lamp filament at the plane of the substage condenser aperture diaphragm, the back focal plane of the objective, and the eyepoint (also … WebReflected light microscopy is often referred to as incident light, epi-illumination, or metallurgical microscopy, and is the method of choice for fluorescence and for imaging … gravity falls grown up
