A dichroscope measures the pleochroism, or refractive nature, of doubly refracting crystals. Wilhelm Karl Haidinger designed the basic form. Our example resembles the improved form introduced in 1881 by Viktor Von Lang (1838-1921), a chemist who served as director of Physikalisches Kabinett in Vienna. The inscription on the light shield reads “R. FUESS STEGLITZ-BERLIN.”
