Object Details
- Franz Schmidt & Haensch
- Description
- This is a solid and substantial instrument of iron and brass. The horizontal circle, 4.25 inches diameter, is graduated by half degrees and read, by verniers with magnifying lenses, to single minutes of arc. The prism is missing. The "Franz Schmidt & Haensch" "Berlin, S." inscription on the circle refers to an optical instrument firm that began in business in 1864, and that trades today as Schmidt & Haensch.
- Franz Schmidt & Haensch described this as a small spectrometer according to Victor von Lang. Von Lang (1838-1921) was a noted crystallographer in Vienna who described the form in the late 1870s.
