Optically butted electro-optical components

An imaging device which comprises lens means for focusing a first focal plane onto a second focal plane along an optical path, optical path dividing means located between the lens means and one of said focal planes for dividing the optical path into at least two optical subpaths leading to corresponding subfocal planes, at least one electro-optical component arranged in each of said subfocal planes, and fixing means for fixing the spatial position of each of said electro-optical components so that said components are correctly aligned relative to the subfocal plane at which it is arranged, in combination, the improvement wherein each of said electro-optical components has at least one pair of lateral surface thereon, and said fixing means comprises an elongated glass member (33) with a mounting surface for each of said components at each of said subfocal planes, and for each said component at least pair of mounting legs each with a base surface (63) and a supporting surface (58, 59) extending in true rectangular relation to such base surface, each of the base surfaces being adhesively bonded to a mounting surface of said glass member and the supporting surfaces of each pair of mounting legs being adhesively bonded to the pair of lateral surfaces on a corresponding electro-optical component.
