Overview

The Spectrometer is spectroscopic angle measurement instrument. It can be used for the angular measurements based on refraction, diffraction, interference or polarization.We offers this high-quality spectrometer that allows students to perform accurate prism and grating spectrometry. High-quality, large-aperture optics produce sharp spectral images, while precision machining allows for precise rotation and accurate measurement.
