Abstract
The present invention is an improved illumination system which achieves enhanced spatial resolution and contrast in the observation of small objects. The enhanced performance is achieved by using a metal-halide light source, a power conservative pre-condenser optics train, an annular diaphragm, a cardioid annular condenser, and an adjustable light-filtering iris. These features are also intended to be used with a direct-view light optical microscope. A method of manufacturing and using the improved illumination system is also disclosed.
