A lens support structure for supporting one or a plurality of optical elements, the structure including a base which may be a passive or an active optical element having one or more grooves formed therein. The structure is intended for use with a laser diode array, for collimating or focusing the emission of the laser diode bars in the array. To this end, the grooves in the base are formed precisely, in a predetermined relationship to the pitch of the grooves in the laser diode array, so that when the array and the lens support structure are matched, the light from the bars in the array reaches the optical elements disposed in the grooves in the lens support structure. The grooves may be formed along one axis, or along orthogonal axes. The optical elements in the grooves may be microlenses. Also, the base may have the grooves formed as slots extending completely through the base, support rails being formed unitarily with the base orthogonally to the slots. Alternatively, the base may be formed of a hollow polygonal structure (preferably rectangular), with at least first and second pairs of opposed sides, grooves being formed in at least one of the first and second pairs of opposed sides.
