Individually Sealed Mounting Holes

All of Newport's optical breadboards are designed with individually sealed 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, 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.

Highly Damped Side Panel

Side panels for optical tables do more than just covers. They should contribute to the overall damping performance of the table. Newport's optical breadboards and tables use highly damped composite wood as side panels to help eliminating vibrations from the side. Composite wood has much better damping performance than steel – it simply does. Materials with a high elasticity (steel, for example, and other hard metals) tend to allow vibration or ringing. Materials with low elasticity such as wood tend to dampen vibration and ringing - For example, hi-fi speakers are almost all enclosed by composite wood to damp the acoustic vibrations.

Low Cost, Light Weight Composite Core

As a more affordable solution, TD series breadboard features a low cost and light weight 20.6 mm precision formed composite core for less demanding applications.

3.4 mm 400 Series Stainless Steel Working Surface

3.4 mm 400 series stainless steel working surface is a more affordable solution than 4.8 mm. When combined with Newport's uniquely designed core structure, the product provides good damping performance and is suitable for majority of the standard optical applications.

Selection Guide

Optical Breadboard Selection Guide

Optical breadboards are selected based on performance criteria like damping and stiffness based on the application. Once the type of breadboard required is determined you can choose the surface size that will support your application.
