Dimension-Labs builds extra-large and special-shaped (multi-section) optical tables by splicing several DL-GJQF1 high-precision air-floating self-balancing tables into one continuous work surface. The spliced surface keeps a uniform M6 hole pattern on a 25 mm grid across the joints.
The models below are standard reference configurations; custom layouts and sizes are available on request. The table top is 12Cr13 ferromagnetic stainless-steel top with M6 tapped holes on a 25 mm × 25 mm grid, flatness 0.1 mm/m² and textured matte finish (Ra 0.8–1.6 µm).
