Abstract
A method of manufacturing a micro molten glass droplet, has the steps of, colliding a molten glass droplet with a micro through hole formed in a plate-shaped member; and pushing out at least part of the glass droplet to a reverse surface of the micro through hole as a micro droplet, thereby forming a glass droplet with a diameter of not more than 5 mm.

A method of manufacturing a micro molten glass droplet, comprising the steps of:
- colliding a molten glass droplet with a micro through hole formed in a plate-shaped member;
- and
- pushing out at least part of the glass droplet to a reverse surface of the micro through hole as a micro droplet, thereby forming a glass droplet with a diameter of not more than 5 mm.
A method of manufacturing a micro optical element, comprising the steps of:
- colliding a molten glass droplet with a micro through hole formed in a plate-shaped member;
- pushing out at least part of the glass droplet to a reverse surface of the micro through hole as a micro droplet, thereby forming a glass droplet with a diameter of not more than 5 mm;
- and
- solidifying the obtained glass droplet by cooling, thereby obtaining a micro optical element.

- pushing out at least part of the glass droplet to a reverse surface of the micro through hole as a micro droplet, thereby forming a glass droplet with a diameter of not more than 5 mm;
- solidifying the obtained glass droplet by cooling, thereby obtaining a material for pressing;
- and
- re-heating the material for pressing, and pressing said material with a mold, thereby obtaining a micro optical element.
A method of manufacturing a micro molten glass droplet, comprising the steps of:
- colliding a molten glass droplet freely dropped from a nozzle, with a micro through hole formed in a plate-shaped member;
- and
- by adjusting any or all of a diameter of the micro through hole, a distance from the nozzle to the micro through hole and a temperature of molten glass, pushing out at least part of the glass droplet to a reverse surface of the micro through hole as a micro droplet, thereby forming a glass droplet with a diameter of not more than 5 mm.
