Advanced Condenser Systems: Achromatic Condensers

Palatine Tonsil

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 substage condenser containing an aperture diaphragm. These photomicrographs are unretouched and were captured with the QX3 interactive software.

Tonsils are small reddish, oval-shaped lumps of tissue, part of the lymphatic system, found in the back of the throat and located on both sides of the uvula. The images below were recorded from a thin section of human palatine tonsil stained with eosin and hematoxylin.

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 Nikon achromatic substage condenser with low numerical aperture.
