Abstract

Two luminescent materials were newly developed to visualize light traces in a convex lens or a concave lens clearly: an infusion of quercus (quercus water) and uranium-glass lenses. A laser pointer that provides a 405-nm purple-light emission was used as the excitation source for luminescence. The aforementioned materials were assembled for the apparatus as follows. (1) A uranium-glass lens was placed in the quercus water, or (2) a uranium-glass lens was placed between two uranium-glass prisms, and then the following light traces were visualized; the incident light, the refracted light in the uranium-glass lens and the transmitted light that passes through the quercus water or uranium-glass prisms.
