    Patent number: 4647155
    Abstract: A multi-layer assembly includes a support block with a plurality of circular cylinder bores, each receiving optical elements. Juxtaposed along the length of each of the bores in a circumferentially spaced-apart relation is a pair of positioning rods having surfaces extending into the bore. The surfaces are precisely aligned with a desired optical axis to be established by the optical element. A plunger pushes the optical element against the rods to establish the optical axis.
