The RG-26-4-ML Research Grade Optical Breadboard with Microlocks has a 2 foot width, a 6 foot length, and is 4.4 inches thick with 1/4-20 holes on a 1 inch grid. The RG Series provides rock-solid stability and rigidity to support demanding research applications. It demonstrates an outstanding <±0.004 in. flatness over two square feet. The RG Breadboard also offers a 3/16 in. ferromagnetic steel surface, two types of constrained layer damping, sealed holes, steel honeycomb core, self-damping side panels, and microlocks.
