Abstract: A photon detector having an optical transparent plate and photodiode array interconnected by an optical light guide array. The optical light guide array including elements providing a transmission line between the optical transparent plate and the photodiode array, where the position of one or more optical light guide elements is formed to adjust for a miss-registered photodiode individual element. A method for assembling the photon detector includes depositing a non-wetting film on opposing surfaces of the optical transparent plate and/or photodiode array, altering the deposited non-wetting film in regions of individual photodiode elements, dispensing an optical coupler adhesive on the optical transparent plate and photodiode array to form adhesive beads, aligning the opposing surfaces, assembling the opposing surfaces so that the corresponding optical coupler adhesive beads contact each other, and curing the optical coupler adhesive to form a structurally merged photon detector having optical light guide elements.
