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 high magnifications of unstained sawdust, which are unretouched and were captured with the QX3 interactive software.
Wood is one of the most important natural resources in the United States.
Until recent years, however, more than half of every tree cut for lumber ended up in waste, wood scraps, chips, shavings, and sawdust. 15 percent of every tree cut into lumber ends up as sawdust. The invention of plywood, a composite of layers of wood, has reduced some of this waste because the wood is stripped off the log in layers instead of being sawed. Semi-transparent and lightly stained specimens are often very difficult to image using unaided brightfield optical microscopy. The images presented here were recorded using the Intel Play QX3 microscope in transmitted brightfield mode.
