Advanced Condenser Systems: Abbe Condensers
Ellagic 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.
Ellagic acid is a bicyclic coumarin derivative that is a naturally occurring phytochemical proven effective in arresting mitosis in some carcinomas. Raspberries, strawberries, and other fruits are rich sources of ellagic acid. Many plants produce ellagic acid in a complex with glucose that forms a family of chemicals known as ellagitannins. These biochemicals are water-soluble and easily absorbed in the diet.
Birefringent Ellagic Acid 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.
