Low-power 3-D microscopes have been available for more than a hundred years, and they can achieve magnifications up to about 50 times. But no high-power 3-D microscopes were available that produced real-time stereo images of the specimen in the magnification range of 100 to 1,500 times. I became so captivated with the idea of developing a 3-D microscope that I resigned from USC in 1991 and cofounded Edge Scientific Instrument Corporation. We developed what was then the only commercially available, high-definition, real-time 3-D light microscope and sold it to research scientists throughout the world.

In order to create the most dramatic images of sand grains, it is important to collect the samples in a special way. Most people collect sand from the dry area of the beach, but the grains from the upper beach can look dull and pitted through the microscope because they have been eroded by the wind. In comparison, sand from the wet portion of the beach has been tumbled by the action of the surf, making the individual grains appear naturally shiny and bright. I normally use fine-grained sand for my images.
