<P>PROBLEM TO BE SOLVED: To provide a planar glass optical element which has excellent forming precision, in particular, has excellent edge surface as the reference of assembling to an optical system and excellent assembling precision, and to provide a manufacturing method having the satisfactory productivity. <P>SOLUTION: Glass in a softened state is integrally press-formed with a die and, thereby, such a formed body that four sheets of planar glass optical elements are arranged adjacently one another and are formed into a two by two matrix shape is obtained. The sheet surface of the side where a cellular lens of the formed body is not formed is optically polished, the formed body is cut off into four sheets of planar glass optical elements and, thereby, the planar glass optical elements are manufactured. The adjacent two end surfaces of the planar glass optical element thus manufactured are formed with the die, the stipulated formed surfaces are obtained and are utilized as the end surfaces becoming the reference of the assembling to the optical system. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
