Title:
PRODUCTION METHOD FOR LIGHT-TRANSMITTABLE COMPONENT AND PRODUCTION SYSTEM FOR LIGHT-TRANSMITTABLE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2020/138357
Kind Code:
A1
Abstract:
This production method for a light-transmittable component (100) comprises: a preparation step (PS1) for preparing a light-transmittable workpiece (100a); a first heating step (PS2) for heating a first area (AR1) including at least a part of the workpiece (100a) to a temperature equal to or higher than a prescribed temperature; and a second heating step (PS3) for heating a second area (AR2), which includes at least a part of the first area (AR1) having been heated in the first heating step (PS2), to a temperature equal to or higher than the prescribed temperature by irradiating the second area (AR2) with light that transmits through the workpiece (100a) at room temperature but is absorbed by the workpiece (100a) at a temperature equal to or higher than the prescribed temperature so as to change at least a portion of the material constituting the second area (AR2) to a state different from that before the heating.
