Microlock tie-downs are a unique innovation that provide versatile and positive mounting of honeycomb optical breadboards above an optical table or directly onto any vertical or horizontal structure. Microlocks include tapped through holes on different locations of the breadboard, as well as the insert to accept 1/4-20 or M6 screws for mounting. The Microlock insert provides a vertical adjustment range of at least 1 in. (25 mm), positive locking of the height, and solid attachment to the primary structure of the optical breadboard for optimum stability. XP Series Breadboard Support Posts or NewDamp™ Elastomeric Vibration Isolators are typically used for mounting a Microlock equipped breadboard at various heights above an optical table.

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. To manufacture a honeycomb core with these advanced features, each piece of corrugated honeycomb steel sheet is emerged in proprietary elastomeric vibration absorbing materials and bonded vertically throughout the height of the core. This labor intensive procedure allows our optical breadboards to offer the highest static and dynamic rigidity, while also increasing point load carrying ability.

All of our optical breadboards are designed with a grid individually sealed 1/4-20 or M6 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.
