The Newport RS4000-46-8 Optical Table is a precision platform engineered for vibration-sensitive optical and photonic experiments. This 4 ft. × 6 ft. × 8 in. thick table delivers exceptional stability through a laminated steel honeycomb core paired with broadband and tuned damping mechanisms. The ferromagnetic stainless steel working surface maintains ±0.004 in. flatness over 2 ft. square, meeting the demands of laser systems, microscopy, and interferometry setups.
