LBTEK provides standard non-magnetic solid aluminum breadboards, which can be used to build compact optical systems. The surface of the breadboard is black anodized to minimize surface reflections as much as possible, reducing the impact on the optical system. The breadboard features an array of standard M6 threaded through-holes with a hole pitch of 25 mm, allowing customers to mount components from both sides. LBTEK’s optical breadboards with a length greater than 300 mm have a total of five counterbored mounting holes. Four of these counterbored holes are located at the four corners of the breadboard, 25 mm from the edge, and the fifth is positioned at the exact center of the breadboard. These five counterbored mounting holes can be used to install vibration-damping rubber pads or other mounting bases, or the breadboard can be mounted onto the surface of an optical table through these counterbored holes. When there is significant load-bearing at the center of the breadboard, adding a mounting base at the central counterbored hole ensures the rigidity of the breadboard surface and reduces deformation. In addition to standard optical breadboards, LBTEK also offers special surface treatment processes, custom sizes, shapes, or drilling services. For any special requirements, please contact LBTEK customer service.
