Newport’s Research Grade 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 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.

Microlock™ Tiedowns

Microlock Tiedowns are the best way to precisely level your breadboard. Microlocks can be used to mount your breadboard on an optical table or directly onto any vertical or horizontal structure. see Breadboard Accessories and Options
