Kirchhoff-Bunsen Spectroscope

Desktop spectroscope for observing and measuring emission and absorption spectra. It features an adjustable slit, a condenser, a flint-glass prism and an observation telescope with a sliding eyepiece. The scale tube carries a reference division that is superimposed on the spectrum's image plane by reflection at the front surface of the prism. A removable prism hood is included, making it ideal for schools and universities.
