Abstract: [Problem]
Provided is an optical element holder which makes it possible to demount an optical element such as a lens therefrom without taking a lot of time and effort.
[Solution]
A lens holder 30 for holding a lens 50 comprises: a frame 32; a lens holding part attached to the frame 32 and configured to hold the lens 50; and a holder mounting part (34, 35) attached to the frame 32 and formed of a magnet-attractable material, wherein the lens holder 30 is mountable to a pallet 16 comprising a pallet-side mounting part formed of a magnet 26, by a magnetic force between the holder mounting part (34, 35) and the pallet-side mounting part.

Abstract: A lens-mold producing method includes a position and posture determining step of specifying positions and postures, in space coordinates, of a first mold having a molding surface for forming one optical surface of a lens and a second mold having a molding surface for forming the other optical surface, a mold holding step of rotating and/or inclining, based on the positions and postures in the space coordinates, at least one of the first and second mold, maintaining a rotation angle and/or an inclination angle of a reference plane of the first mold with respect to a reference plane of the second mold, and holding the first and second mold, and an assembling step of arranging the molding surfaces of the first and second mold so as to face each other, fixing outer peripheries of the first mold and the second mold, and assembling a lens mold.
