ABSTRACT:
An optical device, such as an optical low-pass filter, and a production method therefor, which prevents damage, and thus maintains optical characteristics are provided. The optical device includes a plurality of optical plates joined together with adhesive. The adhesive is spread to extend to the peripheral edge of the optical plates and to the outer periphery of the principal plane surrounding the plurality of optical plates, thus forming a protective coating.
