Optical Benches 1076

The 1033, 1076 and 1088 Optical Benches are constructed from hollow aluminum rectangular beams with heavy wall sections, providing outstanding rigidity for their weight. The surface of the bench, on which optical mounts are supported, is precision machined for flatness to a tolerance of ±0.001"/foot (±0.025 mm/300 mm). The entire bench is hard anodized to provide an extremely hard and long wearing surface that will not corrode. An anodized aluminum alignment bar placed in the center of the supporting surface provides lateral alignment and a versatile clamping surface for the optical mounts. In the center of the alignment bar is a movable stainless steel rack which is part of the rack and pinion system used for remote positioning of components. The alignment bar also holds a steel tape calibrated in both inches and millimeters. The alignment bar is straight to a tolerance of ±0.001"/foot ( ±0.025 mm/300 mm) and ±0.003" (±0.075 mm) over the entire length. The 1033 and 1076 are for the Series 133 and Series 76 respectively, while the 1088 allows mounting of the Series 133 carriers on the top (horizontal) surface and the Series 76 carriers on the side (vertical) surface, simultaneously.
