Optical membrane forming apparatus and optical device produced by the same

Abstract

An optical membrane forming apparatus comprises a vacuum chamber (7), a lens holder (2) placed in the chamber (7) for holding one or more lenses (3) in such a manner that each lens (3) is rotational about its axis, and that the lens holder (2) itself is rotational about its own axis, and a plurality of vaporization sources (10a-10c) placed in the chamber (7). Each of the vaporization sources (10a-10c) produces vaporized particles for forming a layer of the membrane on the surface of the lens (3). The vaporization rate of the plurality of vaporization sources are independently controlled. A diaphragm plate (4) is placed between the vaporization sources (10a-10c) and the lenses (3) in order to control the direction of diffusion of the vaporized particles. Each of the sources (10a-10c) has a sample container which is partitioned into a plurality of rooms to store different samples.
