The images below compare performance of the Intel Play QX3 Computer Microscope with and without the aid of an organized cone of illumination from an achromatic substage condenser containing an aperture diaphragm. These photomicrographs are unretouched and were captured with the QX3 interactive software.

Atropine is an anticholinergic agent that is a potent parasympatholytic, inhibiting actions of acetylcholine at postganglionic parasympathetic neuroeffector sites. It is a competitive antagonist of acetylcholine at smooth and cardiac muscles and various glandular cells. Use of the drug increases heart rate by slowing down some parts of the nervous system while simultaneously speeding up other parts. It relaxes bronchial smooth muscles, therefore reducing airway resistance and dead space. Other effects are an inhibition of salivary secretion and a reduction in motor activity in the stomach and small and large intestines. Side effects include confusion, dizziness, light-headedness, eye pain, and skin rash.

The images above were recorded using the Intel Play QX3 microscope in transmitted brightfield mode equipped with crossed polarizers and a full-wave retardation plate. On the top is a digital image from a stock QX3 microscope using auxiliary illumination provided by a fiber optic light pipe through a hole drilled into the mixing chamber. The image on the bottom was recorded using the QX3 microscope body and a Nikon achromatic substage condenser of low numerical aperture.
