Beamsplitter is one kind of optical element or apparatus which changes one light beam into two or more light beams, and it has been widely used in optical technique. We have already introduced a series ordinary beamsplitter made by using birefringent crystal. In this article we introduce a new series type beamsplitter, that is an adjustable displacement parallel beamsplitter. We can change one light beam into two parallel light beams, and the displacement between the two parallel light beams can be adjusted by using this type of beamsplitter. According to the property of the two parallel light beams, the beamsplitter can be divided into two kinds: the first kind, the two light beams both are polarization light beams; the second kind, the two light beams both are nonpolarization light beams. We have discussed their structure character, working principle and use specification in this article.
