Abstract:
A method for attaching solid-state array image sensors to a color-separation prism comprising:providing three solid-state array image sensor integrated circuits each having a solid-state array image sensor and bonding pads for electrical connections disposed on a same top face thereof, and each said solid-state array image sensor integrated circuit having bonding wires attached to a plurality of said bonding pads; arranging said three solid-state array image sensor integrated circuits in close proximity to output faces of a color-separating prism having substantially equal optical path lengths, each said output face of each said prism having a notch extending from an edge thereof such that said bonding wires occupy a space defined between each said notch and said top face of each said solid-state array image sensor integrated circuit; aligning the three solid-state array image sensor integrated circuits such that images traversing the three paths are coincident within a pixel dimension of the solid-state array image sensors; filling a space between each said output face of the prism and the top face of each corresponding said solid-state array image sensor integrated circuit with index-matched adhesive; and causing the index-matched adhesive to become rigid while maintaining alignment of the three solid-state array image sensors.
