[0033] Figure 1A and Figure 1B is a schematic diagram of a press molding machine corresponding to the apparatus for manufacturing an optical component according to the first embodiment of the present invention. refer to Figure 1A and Figure 1B , reference numeral 2 denotes a mold comprising at least one portion made of an infrared transmissive material (for example, quartz glass). The mold 2 is held by the mold support 1 and is attached to the pressing unit 7 . The pressing unit 7 includes an infrared irradiator 3 including a carbon lamp. Infrared rays 23 (may also be referred to as infrared beams or infrared light) emitted from an infrared irradiator 3 are guided toward a mold 2 through a condenser mirror 4, and thereby applied to a substrate 21 made of resin.
[0034] The intensity of the infrared ray 23 is controlled by the irradiation controller 5 , and the irradiation of the infrared ray 23 to the substrate 21 is controlled on / off by switching the shutter 6 .

[0054] will now refer to Figure 2A and Figure 2B An apparatus for manufacturing an optical component according to a second embodiment of the present invention will be described. Figure 2A and Figure 2B A schematic diagram of a press molding machine corresponding to the apparatus according to the second embodiment is shown. exist Figure 2A and Figure 2B in, with Figure 1A and Figure 1B Parts shown that are the same are denoted by the same reference numerals. Therefore, already described reference numerals used in FIG. 1 will not be described in detail. In this embodiment, the surface 211 of the substrate 21 described in the first embodiment is shaped (shape), and the second surface 212 of the substrate 21 opposite to its first surface 211 is also shaped by the second mold 12. .
[0055] refer to Figure 2A , the second mold 12 is placed on the opposite side of the substrate 21 with respect to the mold 2 . The second surface 212 of the substrate 21 is shaped by...

[0073] An apparatus for manufacturing an optical component according to a third embodiment of the present invention will now be described. Figure 3A and Figure 3B are schematic views of a press molding machine corresponding to the apparatus according to the third embodiment, respectively. and Figure 2A and Figure 2B The same parts as those shown are made with Figure 2A and Figure 2B The same reference numerals as used in are denoted by and will not be described in detail. In this embodiment, an automated hand 24 (eg, a positioning robot) holds and positions the substrate 21 . Other components are basically the same as those described in the second embodiment. A method of manufacturing an optical component according to the present embodiment will be described below.
[0074] Before starting the manufacturing step, the shutter 6 and the second shutter 16 are closed and the infrared irradiator 3 and the second infrared irradiator 13 are turned on in advance.
