Abstract
An optical component is manufactured by precisely measuring the final volume of the optical component, precisely measuring an amount of optical material that will yield that final volume, and discharging it through a nozzle to form a spherically-shaped optical agglomerate, pressing the spherically-shaped optical agglomerate into a disc-shaped optical preform, and then using the disc-shaped optical preform to mold an optical component of a precise final volume. The disc-shaped preform fits stably on a convex upper surface of a lower mold, and the molding operation progresses uniformly and smoothly, thereby yielding a final form optical component.
