Newport’s Research Grade Optical Breadboard provides rock-solid stability and rigidity to support demanding research applications. It is available in two and four in. thickness, and demonstrates an outstanding <±0.004 in. flatness over two square feet. The RG Optical 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 optional microlocks.
