1. A dark-field microscope apparatus comprising:
an objective lens;
a light source;
a dark-field condenser configured to condense light emissions generated by the light source;
a slide housing configured to receive an analytical slide and position the analytical slide between the dark-field condenser and the objective lens; and
an adapter housing configured to removably receive a portable electronic communication device embodying a mobile phone or a tablet computer, the adapter housing comprising a lens receiver configured to receive the objective lens, and the adapter housing being configured to register the objective lens with a camera lens of the portable electronic communication device;
wherein the slide housing is configured to be moved vertically and configured to be selectively engaged to the dark-field condenser using at least one locking element, to permit adjustment of a distance between the dark-field condenser and the analytical slide.
