Abstract
A depolarizer includes a pair of wedge-shaped plates made of an optically isotropic material, laid one on top of another such that the total thickness is constant and wedge-plate holding means for holding the pair of wedge plates separately. The wedge-plate holding means includes a pressure-applying section for applying pressure to each of the pair of wedge plates in a direction perpendicular to the thickness direction of the pair of wedge plates. The pressure-applying direction for one of the pair of wedge plates and the pressure-applying direction for the other of the pair of wedge plates intersect at an angle of 45 degrees.
