Introduction    

There is an increasing demand among universities for a general purpose measuring instrument.

We design this spectrometer to help students to continuously add to their concepts of light and wave phenomena and students may understand the basics of how a grating spectrometer works. The modular structure that makes experiments and tests much easier, are recommended to physics laboratories of institutions of higher learning. The system will measure Hydrogen-Deuterium and Sodium spectrum more accurately than conventional spectrometers. It provides flexible solutions for optical measurements.

Extensive experiments and test measurements have proved that the spectrometer has a high performance in a wide range of applications. It provides flexible solutions for optical measurements. Emission and absorption spectra can be measured. It is also an analytical device in optical filter and light source studies and characterizations.
