Stereomicroscopes have characteristics valuable in situations where three-dimensional observation, depth perception, and contrast are critical. These instruments are also essential when micromanipulation of the specimen is required in a large and comfortable working space. The wide field of view and variable magnification displayed by stereomicroscopes are also useful for construction of miniature industrial assemblies, or for biological research that requires careful manipulation of delicate and sensitive living organisms.
Considering the wide range of accessories currently available for stereomicroscope systems, this class of microscopes remains extremely useful in a multitude of applications. Stands and illuminating bases are available from all manufacturers, and can be adapted to virtually any working situation. There are a wide choice of objectives and eyepieces, enhanced with attachment lenses and coaxial illuminators fitted to the microscope as an intermediate tube. Working distances can range from three to five centimeters to as much as 20 centimeters in some models, allowing for a considerable amount of working room between the objective and specimen. For assembly, inspection, quality assurance, and scientific discovery, there is much to consider about stereomicroscopes.
