Newport offers a wide range of Optical Breadboards to fit any performance, budget or timeline required. Our optical breadboards range from economic Solid Aluminum Breadboards all the way to the top-of-line PG Optical Breadboards. Many of our optical breadboards have Microlock™ option (with -ML at the end of part numbers) or clearance holes to facilitate your applications that may require mounting of the optical breadboard to a table or other platforms.

True Innovation for More Precision: Introducing PG Optical Breadboards
Precision Grade (PG) Series Optical Breadboard is a combination of Newport's persistent innovation and 42 years of experience in vibration control. As the newest member of the Newport Optical Breadboard Family to replace the legacy RG Series, PG series is designed with patented technology to meet requirements of the more critical applications.
Corner compliance of a PG-35-4 breadboard compared to an SG-35-4. The modal damping of the PG series breadboard reduces the resonance by a factor of 9x when compared to an SG series breadboard. Click to Learn More About PG Series Optical Breadboard .Optical Breadboard Spec Comparison

What is Microlock™ option for RG, SG and IG Breadboards?
Microlocks can be used to mount breadboards on an optical table or directly onto any vertical or horizontal structure. They are normally positioned 1/6 of the length/width dimension in from the edge of the breadboard, with an additional Microlock in the center of the boards with larger sizes. With metric mounting holes, the Microlock positions are adjusted slightly to place them directly between the ranks of mounting holes. This provides automatic alignment of the Microlocks with the mounting holes in the supporting table when both the breadboard and the table have the same type mounting holes.
