Optical member manufacturing method, and optical member manufacturing system

An optical member manufacturing system, which is an optical member manufacturing system used to manufacture an optical member having a decorative pattern formed on its optical surface, the system comprising:

• a jig block that supports a base material that is a base of the optical member;
• a data acquisition unit that obtains shape data that specifies an outer shape of the optical member and design pattern data that specifies the decorative pattern to be arranged within the outer shape;
• a three-dimensional measuring unit that measures a three-dimensional shape of a surface to be treated of the base material;
• a laser processing unit that irradiates the surface to be treated of the base material with laser beam in accordance with position control based on the design pattern data while adjusting focus in accordance with a measurement result of the three-dimensional shape, thereby forming the decorative pattern on the surface to be treated;
• and
• a shape processing unit that processes an outer shape of the base material in accordance with the position control based on the shape data, thereby forming the base material into the outer shape of the optical member,
• wherein the measurement of the three-dimensional shape of the base material, the formation of the decorative pattern, and the processing of the outer shape are performed while maintaining a base material supporting state by a jig block that supports the base material, and
• position control for forming the decorative pattern and position control for processing the outer shape are performed while a reference point set in a common coordinate system of the shape data and the design pattern data coincides with a reference point of the jig block that is in the base material supporting state.
