My favorite microscope, is the one I use for Gemstone work. The dark field attachment does not light from underneath; but from every side with diffused light, to reflect off the sample, so you can see the stone better inside. I found some pollen in a piece of Amber with it.:)
Dark-field microscopy
Dark-field microscopy (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.
