Optical Breadboard, Modal Damped, 24 x 36 in., 2.3 in. Thick, 1/4-20

The PG-23-2 Precision Grade Modal Damped Honeycomb Core Optical Breadboard has a 2 ft. width, a 3 ft. length, and is 2.3 in. thick with 1/4-20 holes on 1 in. grid. The PG Series provides rock-solid stability and rigidity to support demanding research applications. It demonstrates an outstanding surface flatness of <±0.004 in. over 2 ft.² . The PG Breadboard also offers a 3/16 in. ferromagnetic steel mounting surface, patented modal damping, sealed holes, steel honeycomb core, and self-damping side panels.

Modal Damping Technology

What makes PG series breadboard the top performance in the industry is an advanced technology called modal damping. This patented technology (US 6,598,545) utilizes two pieces of uniquely designed dampers combined using specially chosen elastomers, to dissipate the vibrations evenly, quickly and effectively. The modal dampers are installed as the side panels along the four sides of the optical breadboard, ensuring the superior damping performance.

Trussed Honeycomb Core with Unmatched Stiffness

Our trussed honeycomb core design maximizes an optical breadboard's rigidity to weight ratio by using an additional steel member to bridge across the center of the honeycomb cells. This design enables a triple core interface at each hexagonal honeycomb cell that is vertically bonded along the height of the core. Most manufacturers use 0.010 in. thick steel sheet for a 0.02 in. core interface, while our trussed design provides a 0.03 in. thick triple core interface for a 50% increase in local rigidity.

Hexagonal Honeycomb Core Advantages

This optical breadboard is designed with a 1 inch grid of individually sealed 1/4-20 threaded mounting holes. Those mounting holes feature 19 mm screw depth. In contrast to some of the other products in the market that has channel for a row of holes or just a polymeric film, our individually sealed holes are more reliable and easier to clean.

Grid of Individually Sealed 1/4-20 Threaded Mounting Holes

This optical breadboard are designed with a 1.0 inch grid of individually sealed 1/4-20 threaded mounting holes. Those mounting holes feature 19 mm screw depth. In contrast to some of the other products in the market that has channel for a row of holes or just a polymeric film, our individually sealed holes are more reliable and easier to clean. This is because we believe in the integrity of the product - especially the core. When dust and liquids go into your optical breadboard and table, it may have a long term effect on the damping performance of the product and make the product degrade over time. A good quality breadboard and table lasts long time - tens of years and more. It's a good investment for a product with sealed mounting holes.
