【Abstract】 The Sr Faraday dispersion optical filter at 460.7 nm in Fraunhofer dip was analyzed. The filtering properties of the filter at line wing and central operation were analysed respectively. The influence of magnetic field, temperature and cell length on the filter operaton was discussed. Under the best operation conditions the transmission at line centre is up to 95%, and bandwidth is about 1.47 GHz.更多还原
