Optical Breadboard, Modal Damped, Microlocks, 12 x 48 in., 4.3 in., 1/4-20
The PG-14-4-ML Precision Grade Modal Damped Honeycomb Core Optical Breadboard has a 1 ft. width, a 4 ft. length, and is 4.3 in. thick with 1/4-20 holes on 1 in. grid. It features Newport designed microlocks that allow users to bolt the breadboard in a most rigid way to another structure. The PG Series provides rock-solid stability and rigidity to support demanding research applications. It demonstrates an outstanding surface flatness of ±0.004 in. over 2 ft.2. The PG Breadboard also offers a 3/16 in. ferromagnetic steel mounting surface, patented modal damping, sealed holes, steel honeycomb core, and self-damping side panels. Specifications
