A segmented mirror with alternating reflective and transmissive surfaces and a refractive tilt place which laterally displaces two parallel beams are used as a beam spacer. A first beam is reflected by the segmented mirror and a second beam is transmitted by the segmented mirror. A third beam is refracted and laterally displaced by the tilt plate then reflected by the segmented mirror while a fourth beam is beam is refracted and laterally displaced by the tilt plate then transmitted by the segmented mirror. The segmented mirror and the refractive tilt plate closely space four parallel laser beams.
