Advanced Condenser Systems: Abbe Condensers

Tylenol (Acetaminophen)

The digital images presented below were recorded with a QX3 microscope body and an Abbe substage condenser equipped for transmitted Rheinberg illumination. These photomicrographs are unretouched and were captured with the QX3 interactive software.

Tylenol is one of over 100 brand names of the analgesic acetaminophen that acts quickly and safely to provide temporary relief of minor headaches, minor muscular aches, overexertion, menstrual cramps, and many other ailments. Acetaminophen is available without a prescription, and is widely used either by itself or in combination with other drugs to produce a wide variety of effects. Side effects include yellow eyes or skin, diarrhea, loss of appetite, nausea, and swelling.

Semi-transparent specimens are difficult to image using unaided brightfield optical microscopy. The images above were recorded using the Intel Play QX3 microscope in transmitted brightfield mode with the assistance of Rheinberg illumination. Dyed acetate gel filters were strategically placed below the aperture diaphragm of an aftermarket Abbe-style condenser to generate the Rheinberg effect. A 15-millimeter central filter was surrounded by a larger annular filter to combine the effects of oblique specimen illumination by light filtered through the annular filter superimposed over a background of light filtered through the central filter.
