Combination Low Magnification Dark-Field Illuminator and Bright-Field
Microscopy Substage Condenser with Descriptions and Modifications to
Manufacture this Device from Commercially Available Fiber-Optic Ringlights

In June 2003, intellectual property artwork and prototype demonstration for a Combination Low
Magnification Dark-Field Illuminator and Bright-Field Microscopy Substage Condenser were filed
pursuant of US patent. Prior-art drawings, prototype description, and modification instructions
for the manufacture of this device from commercially available fiber-optic ringlights were filed
through the UT Southwestern Office of Technology Development.

This combined illuminator and condenser device improves low-magnification illumination of
biological, synthetic, or mineral samples viewed through a microscope or dissecting scope.
The device, and methods described to manufacture this device by modifying commercially
available fiber-optic ringlights, facilitates improved low-magnification microscopic
analysis and/or photography of hydrated or dissected whole samples, portions of samples
that have been thinly sliced or thinly polished, and paraffinized or deparaffinized
histologic sections which may be stained or unstained.

Currently, this illumination technology is unlicensed. Parties interested in this technology
may contact the inventors (John Shelton, James Richardson and George Grauer) through the
Office of Technology Development at UT Southwestern and reference UTSD1494.
