the stage, rotate the knob(7); for moving forward and backward the stage , rotate the 

knob(6). 

4.Adjustment  of  separation  line:  The  separation  line  should  be  a  fine  and  black 

straight one. Turn the separation line adjusting knob(12) to move the separation line, 

you  may  get    the  left  and  right  single  viewfield  observation,  cutting-image    and 

superimposed-image  comparison.  When  black  and  white  line  are  wider  ,  rotate  the 

black  screw  at  the  right  of  the  knob(12),  when  width  are  not  identical  ,  rotate  the
