Optical Breadboards

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.

What is Microlock™ option for PG, 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.
