Advanced Condenser Systems: Abbe Condensers

Thiorphan 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.

A well-documented biochemical inhibitor, thiorphan is best known as an anti-kephalin. Kephalin is one of several naturally occurring morphine-like substances found in the brain. Thiorphan is being actively researched for potential uses as a medication for asthma and diarrhea. As an inhibitor of neutral endopeptidase/enkephalinase, thiorphan has been found to enhance cell proliferation in bone marrow cultures of patients with acute leukemia in remission.

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.
