This unit is a spectrometer in which the collimator and telescope are held fixed and the observed wavelength is varied by rotating the prism or diffraction grating. It is specially suited to industrial and experimental work. Constant Deviation Wavelength Spectrometer is Direct reading for the study of spectral series viz., Emission spectra of elements, Absorption spectra of compounds, Fluorescence spectra, Band spectra zee man effect, Raman spectra, quantitative spectrum analysis etc, fitted with EDF Prisms read by rotatable wave length drum, eye pieces with scale of LC 0.01cms. Achromatic objective of high resolution, variable slit opening read by micrometer. Complete with Arc. & Spark Lamp.
