About This Product
After focusing the telescope and aligning the collimator slit with the light source, students rotate the telescope to find the direct and deviated images and read the angular positions. The readings give refractive index by minimum deviation, dispersive power of a prism, or wavelength with a diffraction grating. Educational Instrument can arrange export supply of the Spectrometer to Nicaragua, Uzbekistan, Dominican Republic, Djibouti and Belgium.
