LumaScope

he LumaScope is a low priced, small USB inverted fluorescence microscope. It was conceived and designed by working scientists who realized that a large proportion of the everyday uses of fluorescence microscopy is to check the presence, health, and signal from labeled cells. Traditional inverted scopes are expensive, complicated, and loaded with features that are not required for these tasks. The LumaScope focuses on:portability, small size, ease of use, continuous availability, and low price. Perfect when you can do without the cost and complexity of a typical, full-sized fluorescence microscope.
