Accurate Faraday Measurement System for PBB Glasses in Current Transducer Application

An optical-electronic system for Faraday rotation measurement is designed and constructed to evaluate the verdet constant of magnetic -optical glasses. The works include the optical bench setup and development of software. PbO-Bi2O3-B2O3 glasses systems were fabricated and characterized by using the self-constructed optical bench and the obtained Verdet constants @632.8nm for glass PBB1 was verified by using a commercial powermeter (as detector). The developed measurement system showed characteristics of low cost, small size and accurate.
