Optical element manufacturing apparatus

An optical element manufacturing apparatus comprising:

• a plurality of pairs of stage units which are configured to have a mold set that houses a molding material transferred through the pairs of stage units along a first direction;
• wherein:
• each of the pairs of stage units comprises two stage units that are arranged opposite to each other along a second direction, which is perpendicular to the first direction, and are configured to sandwich the mold set;
• each of the pairs of stage units is configured to perform at least one of heating, pressurization, and cooling on the mold set;
• each of the stage units includes a temperature control block;
• the temperature control block of at least one of the stage units comprises two heating regions in which heating sources are arranged, and a non-heating region that is positioned between the two heating regions and in which no heating sources are arranged;
• and
• in the temperature control block of the at least one of the stage units:
• each of the heating regions is a region that extends continuously across the entire temperature block in the first direction;
• the non-heating region is a region that extends continuously across the entire temperature control block in the first direction;
• the two heating regions are positioned at two ends of the temperature control block, and the non-heating region is positioned at a center of the temperature control block between the two heating regions so as to separate the two heating regions from each other, along a third direction which is perpendicular to both the first direction and the second direction;
• the heating sources are provided in the heating regions on both sides of the non-heating region along the third direction;
• the non-heating region is a region without any heating sources across the entire temperature control block in the first direction and without any heating sources between the two heating regions along the third direction.
