About This Product
A spectrometer is used to measure angles accurately in optics experiments. Light from the slit passes through the collimator as a parallel beam and meets the prism on the table. The telescope is then turned to find the refracted or dispersed rays, and the circular scale with its vernier gives the angle. In school and college physics labs it is used to find the angle of a prism, the angle of minimum deviation and the refractive index, and to observe spectra.
Frequently Asked Questions
