About This Product
Light from a source such as a spectrum lamp passes through the collimator to a prism or diffraction grating on the table, and the telescope position is read from the verniers to measure the angles of the spectrum. Lines on the table help position the prism relative to the levelling screws. The supplied accessories are a diffraction grating holder, hand magnifier, prism clamp, tommy bar for adjusting the optical axes and a plywood case, with setting up instructions. Export supply of the Spectrometer - Intermediate can be arranged to laboratories and schools in Poland, Samoa, Lebanon, Guinea-Bissau and Liberia.
