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.
Birefringent Thiorphan Crystallites
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.
