O p t i c a l Ta b l e s a n d V i b r a t i o n C o n t r o l 1011 Email: sales@newport.com • Web: newport.com TECHNICAL REFERENCE OPTICAL TABLES HONEYCOMB, GRANITE AND RIGID STRUCTURES BREADBOARDS AND GRID PLATFORMS ISOLATORS WORKSTATIONS AND ISOLATED PLATFORMS STRUCTURAL RAILS AND CARRIERS TESTING, ANALYSIS AND DESIGN RG Series Research Grade Breadboards with Constrained Layer Damping 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. • Selectively eliminates torsional and bending table modes • Damped work surface eliminates skin resonance • Honeycomb cells for a lighter, stiffer table with better dynamic rigidity • Triple core interface increases point-loading capability while minimizing static deflection Specifications Working Surface 400 Series ferromagnetic stainless steel 3/16 in. (4.8 mm) thick with integrated damping layer Thickness [in. (mm)] 2.4 (59); 4.4 (112) Surface Flatness [in. (mm)] ±0.004 (±0.1), over 2 ft (600 mm) square Core Design Trussed honeycomb, vertically bonded closed cell construction, 0.010 in. (0.25 mm) Steel sheet materials, 0.030 in. (0.76 mm) triple core interface Broadband Damping Contrained layer dampers and Integrated Damping* Mounting Hole Type Cut (not rolled) threads with countersink 1/4-20 holes on 1 in. grid (M6-1.0 holes on 25 mm grid), 0.5 in. borders (12.5 mm borders) Hole/Core Sealing Easy clean conical cup 0.75 in. (19 mm) deep Non-corrosive high impact polymer material Microlocks Option Number of Microlocks 4 for breadboards 3 ft2 (0.27 m2) 5 for breadboards >3 ft2 (0.27 m2) Locations W/6 from long side; L/6 from short side Typical Performance Values Maximum Dynamic Deflection Coefficient <9.4 x 10-4 Maximum Relative Motion Value [in. (mm)] <7.3 x 10-7 (<1.9 x 10-5) Deflection Under Load [in. (mm)]= <7.8 x 10-5 (<2.0 x 10-3) Note: All performance values are for 2 ft x 3 ft x 2.31 in. (600 x 900 x 59 mm) breadboards. =50 lb (22.7 kg) centered * Integrated Damping includes constrained layer core, damped working surface and composite edge finish. 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 page 1019
