Advanced Condenser Systems: Abbe Condensers

Malonic Acid Crystallites

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

Malonic acid is an organic dicarboxylic acid with a methylene group separating the two carbonyl moieties. The diethyl ester of malonic acid is used in the syntheses of several vitamins, barbiturates, and numerous other organic compounds. The free acid is rather unstable and has few uses other than being a biochemical diagnostic probe for intermediary metabolism.

QX3 with mixing chamber (stock - 200x magnification)

QX3 with achromatic condenser (200x magnification)

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 simple two-lens Abbe low numerical aperture substage condenser.
