Claim:
A lens array comprising: a first lens section, comprising a first surface and a second surface, said first surface comprising a first plurality of lens surfaces, said first plurality of lens surfaces forming a first plurality of optical axes, said first plurality of lens surfaces having substantially the same size and shape, said second surface comprising a second plurality of lens surfaces, said second plurality of lens surfaces forming a second plurality of optical axes, said second plurality of lens surfaces having substantially the same size and shape, such that each optical axis of the first plurality of optical axes is aligned with an optical axis of the second plurality of optical axes; a second lens section, comprising a third surface and a fourth surface, said third surface comprising a third plurality of lens surfaces, said third plurality of lens surfaces forming a third plurality of optical axes, said third plurality of lens surfaces having substantially the same size and shape, said fourth surface comprising a fourth plurality of lens surfaces, said fourth plurality of lens surfaces forming a fourth plurality of optical axes, said fourth plurality of lens surfaces having substantially the same size and shape, such that each optical axis of the third plurality of optical axes is aligned with an optical axis of the fourth plurality of optical axes; a spacer section, having a spacer thickness, comprising a first plurality of holes of circular cross section, said first plurality of holes having a first plurality of axes; and a stop, having a stop thickness, comprising a second plurality of holes, said second plurality of holes having a second plurality of axes; such that each optical axis of the second plurality of optical axes is aligned with an optical axis of the third plurality of optical axes, and each axis of the first plurality of axes is aligned with an optical axis of the third plurality of optical axes, and each axis of the second plurality of axes is aligned with an optical axis of the first plurality of optical axes; and such that the stop is disposed against the first surface of the first lens section, the second surface of the first lens section is disposed against the first surface of the spacer section, and the second surface of the spacer section is disposed against the first surface of the second lens section.
