WebDiascopic fluorescence microscopy requires the use of a dark field condenser. Dry dark field condensers can have a maximum NA of 0.95 and they must be used with objective lenses of NA less than 0.75. Oil dark field condensers may have an NA as high as 1.4 and can be used with objectives of NA less than 1.1. Standard paraboloid and cardioid dark ...

This … Dark-field microscopy (also called dark-ground microscopy) describes microscopy methods, in both light and electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e., where there is no specimen to scatter the beam) is generally dark. In optical … See more In optical microscopy, dark-field describes an illumination technique used to enhance the contrast in unstained samples. It works by illuminating the sample with light that will not be collected by the objective lens and thus will not … See more Dark-field studies in transmission electron microscopy play a powerful role in the study of crystals and crystal defects, as well as in the imaging of individual atoms.
