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