These spacers, which are based on the outer profile of our BA2 Mounting Plate, are available in an array of thicknesses and are manufactured to facilitate changes in beam heights. The three thinnest spacers are fabricated from stainless steel while the five thickest ones are fabricated from black anodized aluminum. Each spacer is equipped with two counterbored mounting slots that accept 1/4"-20 (M6) capscrews and an arrangement of tapped, clearance, and/or through holes (see the tables below for details). The configuration of holes and slots provided makes it easy to bolt multiple plates together and to create fixed-height optical systems.
