The top and bottom skins as well as the trussed honeycomb core of the RPR-N are constructed from virtually non-magnetic 316 series stainless steel, which contains less iron than the ferromagnetic 430 stainless steel used in standard tabletops and therefore has very low responsiveness to magnetic fields. The RPR-N Non-Magnetic Series offers the same dynamic performance, static rigidity, and thermal stability capabilities as the RPR Series. The RPR-N is an ideal solution for supporting large vacuum chambers or other heavy instruments used in materials research applications. In extreme applications where it is essential that all magnetic materials be removed the RPR-N Series is the best choice due to its 316 non-magnetic stainless steel construction. Newport also offers non-magnetic S-2000AN isolators.

Newport's honeycomb core is different than our competitors. Each piece of the corrugated honeycomb steel sheet is emerged in proprietary elastomeric vibration absorbing materials and bonded vertically throughout the height of the optical breadboard or optical table, creating a much stiffer honeycomb core structure. This labor intensive procedure makes sure that Newport's optical breadboard or optical table has the most robust honeycomb structures.

All of Newport's optical breadboards and tables are with individually sealed mounting holes. Those mounting holes feature 19 mm screw depth and in contrast to some of the other products in the market that has channel for a row of holes or just a polymeric film, Newport's 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.

Side panels for optical tables are more than just covers. They should contribute to the overall damping performance of the table. Our optical tables use highly damped composite wood as side panels to help eliminate vibrations from the side. Composite wood has a much better damping performance than steel. Steel has a high elasticity and tends to allow vibration or ringing. Materials with low elasticity such as wood tend to dampen vibration and ringing. For example, home stereo speakers are typically enclosed by composite wood to damp the acoustic vibrations.

Our S-2000AN non-magnetic pneumatic isolators are designed specifically for use with our RPR-N non-magnetic optical table tops. Featuring virtually non-magnetic components and the robust design of S-2000A isolators, S-2000AN isolators are your ideal choice for non-magnetic applications. Uniquely designed features such as hybrid chamber, laminar flow damping technology and adjustable height make S-2000AN the best in isolation specifications and ease of use in the market.
