A Spectrometer is a high-precision optical instrument used to analyze the spectrum of light and to measure the angle of deviation, wavelength, and refractive index of light through prisms or diffraction gratings. It is a crucial device in physics and optics experiments.
Material: Sturdy metallic base with fine mechanical adjustments
Telescope & Collimator: Adjustable, with fine focus and optical alignment
Vernier Scales: Dual vernier readouts for high angular resolution (usually 1' or 0.5')
Prism Table: Circular, rotatable and adjustable in height and level
Wavelength Range: Visible light region (with standard sodium or mercury lamp)
Determination of refractive index of prism materials
Measuring angles of a prism (angle of minimum deviation)
Study of spectral lines using diffraction grating
Important in CBSE/ICSE/State board, B.Sc., and engineering optics labs
Used in research, teaching, and spectral analysis
