In order to obtain symmetry and parallel polarized light, the double Wollaston prism is amended. After getting symmetric polarized light at a big splitting beam angle, an ordinary triangular prism is added so that the symmetric light beam can be divided into parallel light beams.The distance between the triangular prism and the double Wollaston prism is changed so that the distance of the shearing parallel light can be changed.The measured transmittance of the new beam splitter is about 85% with measurement error of about 0.91 %.It saves material and saves the measurement time. It is able to meet the needs of more sophisticated measurement.
