Non-Magnetic RPR-N Reliance™ optical table tops feature the broadband damping, material workmanship, and quality found in our standard optical tables while meeting many non-magnetic application needs. The top and bottom skins as well as the trussed honeycomb core are made with virtually non-magnetic 316 series stainless steel. The RPR-N is an ideal solution for supporting large vacuum chambers or other heavy instruments used in materials research applications.

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.
RPR Reliance™ broadband damped optical tables represented the state of the art before the advent of tuned damping found in our RS2000 and RS4000 Series optical tables. Indeed, the RPR set the standard that younger companies still imitate. Today they still offer good value for many less stringent applications. The RPR Series tables offer great performance and quality at an affordable price. RPR Reliance™ optical table tops feature a 4.8 mm thick optical table skin, a constrained layer core, damped working surface and composite edge finish to provide broadband damping.
The compliance curve shows the positional motion of the structure for a given excitation force and frequency. The red line is the rigid body line showing how an ideal optical table would perform with no relative motion. The blue line shows the natural frequencies of the optical table and how they deviate from that of a rigid body.
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 Newport tables are vertically bonded along the height of the honeycomb core. Most other manufacturers forego this extra step because of added expense and time required to apply adhesive to each individual core member. Vertical bonding adds constrained layer damping effects into the core, while maximizing the table’s rigidity-to-weight ratio. The trussed core design enables a triple core interface at each honeycomb cell. Whereas open core designs only have two structural members at each interface, the Newport table has three offering a 50% increase in local rigidity. The three sheets are fully bonded for the full table height producing greater stiffness.
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.
The 1/4-20 or M6 tapped mounting holes are countersunk and deburred. This ensures easy thread engagement while eliminating contamination problems. The mounting holes are located on a 1 in. or 25 mm grid with standard grid markings for easy and repeatable component placement.
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.
Metrology quality steel assembly platens are used to ensure the superior flatness of our optical tables. The platen supports the top surface of the table during the assembly and bonding process and imprints the top surface with the same flatness characteristics. Our platens are the largest and flattest in the industry. We use gravity pressure bonding to apply constant pressure across the optical table during the bonding process ensuring that the top surface conforms to the platen flatness.
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.
