Our Aluminum optical breadboards have 3/16″ thick aluminum skins laminated to a nonmetallic honeycomb core. Our breadboards have greater than 50% direct core to metal skin lamination providing a strong bond and static rigidity. The core has 3/8″ honeycomb cells with inherent broadband energy absorption, eliminating the need for additional internal dampers to suppress the resonance found in metal cores. Holes are sealed with a polymeric film that punctures when used, allowing the full depth of the breadboard to be used.
Flatness: 0.01″ over 1′ cumulative distance. Entire breadboard coated in a black anti-reflective finish. We offer these breadboards in 4″, 2″, 1″ and 1/2″ core thicknesses.
