LGS-5 Spectroscope

Introduction   The Spectrometer is spectroscopic angle measurement instrument. It can be used for the angular measurements based on refraction, refraction, diffraction, interference or polarization. For examples: 1) Measurement of prism angle Based on principle of reflection. 2) Min-deviation measurement of prism based on principle of refractive, computation of refractive index and dispersion of the material by which the prism is made. 3) Wave-length measurement and demonstration of the diffraction phenomenon in interference experiment when in conjunction with the grating. 4) Being used for the experiment of polarization using, zone plate and polarize. Main configuration and parameters: Using the principles of reflection, refraction, diffraction and interference, angle measurement is made in various experiments.   Specifications 1) Angle Measurement Accuracy 1’ 2) Optical Parameter: Focal Length 170mm Effective Aperture Ф33mm Field of View 3°22’ Focal Length of Telescope’s Eyepiece 24.3mm 3) Max.
