SG Series Scientific Grade Breadboards

Product catalog summary

Technical Reference Overview
This document provides detailed specifications and ordering information for optical tables and vibration control products, including breadboards and platforms. It covers both the RG (Research Grade) and SG (Scientific Grade) series, highlighting their features, performance, and customization options.

Specifications
The working surface is made of 400 Series ferromagnetic stainless steel with integrated damping. The thickness options are 2.4 inches (59 mm) and 4.4 inches (112 mm), with a surface flatness of ±0.004 inches (±0.1 mm) over a 2 ft (600 mm) square. The core design features a trussed honeycomb structure with vertically bonded closed cell construction. The mounting holes are cut threads with countersink, available in 1/4-20 holes on a 1-inch grid or M6-1.0 holes on a 25 mm grid.

Performance Values
The maximum dynamic deflection coefficient is less than 14.4 x 10^-4, and the maximum relative motion value is less than 11.1 x 10^-7 inches (2.8 x 10^-5 mm). Deflection under load is less than 7.8 x 10^-5 inches (2.0 x 10^-3 mm). These values are based on a 2 ft x 3 ft x 2.31 in. (600 x 900 x 60 mm) breadboard with a centered 50 lb. (22.7 kg) load.

Ordering Information
To order, use the format: Model RG-WL-T-Width x length (in ft.) ML (Microlock option) Thickness (2 or 4 in., add N for no holes). For metric mounting holes, add an M- in front of the model number. Example: RG-24-2-ML designates a 2 ft x 4 ft RG Breadboard, 2 in. thick, with Microlocks.

Standard Sizes
Available sizes range from 1 x 1 ft (300 x 300 mm) to 4 x 8 ft (1200 x 2400 mm). Special sizes can be requested.

SG Series Features
The SG Series is similar to the RG Series but lacks constrained layer dampers. It includes a 3/16 in. ferromagnetic steel surface, enhanced damping, sealed holes, and a steel honeycomb core. It offers superior performance compared to other manufacturers' top-of-the-line breadboards.

Microlock Tiedowns
Microlock Tiedowns are used for precise leveling of breadboards and can be mounted on optical tables or any vertical or horizontal structure.

SG Series Scientific Grade Breadboards Newport’s Scientific Grade Breadboard is identical in all ways to our Research Grade Breadboard, except that it is not equipped with constrained layer dampers. The SG Breadboard offers a 3/16 in. ferromagnetic steel surface, enhanced damping, sealed holes, steel honeycomb core, and optional microlocks. This means the SG Series still out-performs other manufacturers’ top-of-the-line breadboards. • 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 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
