ABSTRACT:
A hologram which is made by use of a collimated light beam incident upon the hologram at an angle with respect to the line orthogonal thereto is used as an optical element to converge a laser beam in a process of making a hologram lens. Since the hologram made by use of the obliquely incident collimated light beam has a large effective area, a hologram lens having a large effective diameter can be produced.
