Summary: | PROBLEM TO BE SOLVED: To enable even a large-sized optical member to be easily and accurately positioned and assembled as for the assembly method of an optical device, the assembly method of an exposure device using it, the assembly device of the optical device and the assembly device of the exposure device using it. SOLUTION: Since the optical member D2 is positioned on a condition that the load thereof imposed on the other member D1 is reduced, friction occurring between the optical member and the other member because of the load of the optical member is also reduced. Thus, the optical member can be easily relatively moved with respect to the other member. |
