Abstract

A method is provided for assembling an optical collimator array. The method begins by directing light through a first optical collimator to produce a first optical output beam. The first collimator is supported by a first carrier element. The first collimator is rotated about its central longitudinal axis to adjust a position of the first optical output beam on a surface that intercepts the first optical output beam. The first carrier element is then rotated about a carrier axis perpendicular to the central longitudinal axis and in a plane containing the central longitudinal axis to further adjust the position of the first optical output beam on the surface. The first collimator continues to be rotated about these axes until the first optical output beam is located at a desired position on the surface, at which point the first optical collimator is secured to the first carrier element. Next, the first carrier element itself is secured to prevent rotation about the carrier axis. The aforementioned steps are repeated for a second optical collimator producing a second optical output beam, which is supported by a second carrier element. The second optical collimator continues to be rotated about the two axes until the second optical output beam is located at a second position on the surface that is offset from the position of the first optical output beam by a prescribed amount. Finally, the second optical collimator is secured to the second carrier element and the second carrier element is secured to the first carrier element.
