<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a compound prism by which sticking mistake can be prevented when two or more wavelength plates are stuck together onto a prism coupling body. <P>SOLUTION: A groove 11 is formed on one main surface of a 3rd laminated body 8 along a lamination surface 8c of the 3rd laminated body 8 from one end to another end and further a level difference part 12 is formed at one end of the 3rd laminated body 8. Then a 1st wavelength plate 16a and a 2nd wavelength plate 16b are stuck together with the groove 11 and the level difference part 12 as references. <P>COPYRIGHT: (C)2008,JPO&INPIT |
