About This Product
The instrument can be used for quantitative optical measurements. A prism or diffraction grating is placed on the levelled table, light from the slit passes through the collimator, and the telescope is turned to view the result through the cross-wire eyepiece. Angles are read from the rotating scale with the vernier on the telescope mount. Beyond India, the Spectrometer is available for export to Central African Republic, Sierra Leone, Côte d'Ivoire, United States, Cabo Verde and Mali.
