Name: Medium-Precision Air-Floating Self-Balancing Optical Table
Brand: Dimension-Labs
SKU: DL-GJQF2-0906-05
Availability: InStock

The DL-GJQF2 series is an air-floating (pneumatic) vibration-isolated optical table with automatic self-leveling, offering good vertical and horizontal isolation at a lower cost than the DL-GJQF1 series. Floor vibration at 5 Hz and 10 Hz is reduced by about 80% and 96% respectively, suitable for most optics and laser laboratories.

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).

Table Construction

Welded steel-grid core: 6 mm steel plates welded into a cross-grid core and stress-relieved by high-temperature tempering and ageing. Heavy and very rigid, with minimal deflection under heavy loads and no risk of debonding. 22 standard sizes from 900 × 600 mm up to 6000 × 1500 mm.
Bonded honeycomb core (models ending in -A): Stainless top plate, sealed isolation-cup layer, bonded honeycomb core and steel bottom plate. Lighter and easier to move and install; the dust-proof cups stop liquids and debris entering the core and block air flow between tapped holes. 13 standard sizes from 900 × 600 mm up to 2400 × 1500 mm.
