| 摘要 |
The present invention is a method of producing an optical element that ensures satisfactory geometric precision, even in a case where multiple optical elements are molded. By providing a raised portion (12d) for changing the flow of optical element glass droplets (GD) melted into a molding die (10), the optical element glass droplets (GD) can be made to flow along an optical surface transferring surface (12a) at an outer edge of the optical surface transferring surface (12a) closer to the dripping point of the optical element glass droplets (GD). Accordingly, even in a case where multiple glass lenses (100) are molded in bulk, an optically functional surface (101a) of the glass lens (100) in each optical surface transferring surface (12a) can be transferred with high precision, and glass lenses (100) of satisfactory geometric precision can be produced in bulk. |
