467231 Spectrometer and Goniometer
Spectrometer and Goniometer For observing and measuring emission and absorption spectra. With a precise scale for measuring the angle of deflection for prisms and gratings; thus also suitable for determining the refractive index and mean dispersion. With an adjustable slit, condenser, flint glass prism, telescope and illuminated cross-wires. A holder for the metal line grating (471 51) can be used instead of the prism table.
