Quick Overview

For the precise determination angular position, particularly of optical spectra. Can also be used as a spectroscope for the observation and measurement of emission and absorption spectra. When used with a prism, students can observe visible light as it is dispersed by wavelength. When used with a diffraction grating and a gas discharge tube, students can observe the emission spectrum of various gases. The wavelengths of each electron transition in the spectrum can be calculated according to the angle of deflection of the light traveling through the grating. The Advanced Spectrometer-Goniometer illustrates the concepts behind discovering the properties of astronomical objects such as chemical composition or velocity. Features: Collimator
