A dark field microscope uses light coming in from the side to illuminate the particles. What it is viewing is the Rayleigh scattering ( Tyndall ) from each particle. Since only particles approximately the wavelength of light and larger can be imaged, but particles 1/1000 the wavelength of light can scatter the light causing tyndall, it allows one to see particles that are much too small to be seen with a conventional microscope. The other side of the coin is that for all practical purposes such small particles will always appear as a dot approximately the wavelength of the light no matter what their shape if they are under a wavelength of light in size.
