<p>Disclosed is a glass distinguishing apparatus which can distinguish different glasses all having approximately the same color from each other. The apparatus comprises: a cell (20) for accommodating a material to be distinguished (10) composed of multiple glasses all having approximately the same color in a mixed state and an immersion solution (100) having approximately the same refractive index as that of a specific glass (11); a floodlighting unit (30, 50) for floodlighting the cell (20); a specific glass transmitted light detection unit (41) for detecting a specific glass-transmitted light (11a) which is transmitted through the specific glass (11); and a different glass-transmitted light detection unit (42) for detecting a different glass-transmitted light (12a) which is transmitted through a different glass (12) from the specific glass (11) to show a polarized light pass, based on the difference in refractive index between the specific glass (11) and the different glass (12).</p> |
