A near infrared potassium Faraday anomalous dispersion optical filter was theoretically studied for the transition, including hyperfine ef fects. In the paper the Zeeman splittings of potassium were calculate d for the given transition, that is, diagonalizing the disturbed matri x, and finding out the Zeeman sublevels position and transition freque ncies. Next we obtain an expression for the bulk polarizability tensor . Finally we acquire the transition coefficient relating to the polari zability tensor. The effect of temperature and magnetic field on prope rties of Faraday optical filter were investigated. The optimum filter operating condition was also obtained. The single peak bandwidth of th e optical filter is about 0.86GHz, equivalent noise band width is 2.4G Hz. The transmission is approximately 94.1 percent under the optimum c ondit ion.
