                          two prisms can expand or contract the beam in one direction 
                          without any changes in the other direction. By adjusting 
                          the angles among the incident beam and two prisms, the 
                          shape of the beam can be changed. It is very easy to 
                          turn elliptical bean into circular beam. |  |
