Designed with a 12.7 mm thick aluminum plate, these breadboards maintain consistent flatness across the entire surface. The thickness is ideal for preventing warping or flexing, ensuring long-term stability. Their non-magnetic properties make them suitable for sensitive optical setups where the influence of magnetic fields needs to be minimized.

The breadboards feature a double-density hole pattern with M6 tapped holes placed at a 25 mm center spacing. This increased hole density provides more flexibility for securely mounting optical components, instruments, and other equipment, allowing for easy adjustments and precise positioning. The 1-inch (25.4 mm) spacing along the outer edge ensures compatibility with a wide range of optical posts, mounts, and fixtures.
