Experimental System for Electro-Optic Modulation

This electro-optic modulation experiment system is designed to study the interaction between electric fields and light using the electro-optic effect. It enables students to investigate electro-optic modulation, measure the half-wave voltage and electro-optic coefficient of an electro-optic crystal, and demonstrate optical communication principles. The system provides a comprehensive platform for experiments in laser technology, optical signal processing, and optical communication. Manufactured by Atico Export India.
