Intermediate Spectrometer Goniometer Optics Educational Kits

The Intermediate Spectrometer Goniometer is a precision optical instrument designed for spectroscopy, diffraction, refraction, and angular measurement experiments. Equipped with a rotatable telescope, collimator, precision graduated scale, and stable specimen stage, the system enables accurate optical measurements for physics and optics laboratories. The apparatus allows students to investigate prism optics, diffraction gratings, spectral analysis, refractive index determination, and material dispersion characteristics. Its precision mechanical construction and vernier reading system ensure reliable and repeatable measurements, making it suitable for both educational and research applications. With an optional Hydrogen-Deuterium lamp, the instrument can also be used for atomic spectroscopy experiments, including measurement of Hydrogen spectral lines and determination of the Rydberg constant.
