Honeycomb Optical Breadboard, 4.8 mm Skin, 36 x 48 x 2.3 in., 1/4-20, Microlocks
The SG-34-2-ML Scientific Grade Honeycomb Core Optical Breadboard with Microlocks has a 3 foot width, a 4 foot length, and is 2.3 inches thick with 1/4-20 holes on a 1 inch grid. The SG 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 SG Breadboard offers a 3/16 in. ferromagnetic steel surface, enhanced damping, sealed holes, steel honeycomb core, and microlocks. This means the SG Series still out-performs other manufacturers’ top-of-the-line breadboards. Specifications
