Spectrometer is an instrument used to study the spectra of a material as well as to find its refractive index also. This is done by producing spectral lines and after that, wavelengths and intesities can be measured.

Sigma Spectrometers stand on top when it comes to quality, accuracy and workmanship. Our Spectrometers are exclusively provided with a buil in light system to read the Vernier scale. The light system in our Spectrometers is unique in its class and adequate in terms of illumination, enabling the user to read the Vernier scale easily. Our Spectrometers are checked tested and aligned in such a way that the optic axis of collimator and telescopes pass through the vertical line in the center of the prism table through the same point at all positions of the telescope.

1. 6" Scale Diameter.
2. Best quality achromatic objectives of 7 focal length and 1 diameter and 10x eye piece with sharp cross lines are used.
3. Sharp adjustable brass slit is provided on the collimator tube.
4. Central cone bearing system gives smooth round motion to the moving body on which scale and telescope are fixed.
5. The central brass axle on which the verniers are mounted is tapered in shape ensuring accuracy for all times.
6. A spring loaded prism table is very accurately placed in the center of the scale.
7. Built in Light Syatem to read the Vernier scale.
