Overhead optical table shelf systems maximize lab space by providing an easily-accessible shelf directly above the table surface for electronic equipment typically used for an optical experiment. The shelf is made for equipment like laser power supplies, motorized stage controllers, oscilloscopes, computers, and other instruments like power meters. Abundant electrical outlets are mounted on both sides of the overhead shelf allowing easy access to power. These overhead shelves are free standing and do not make contact with any part of the optical table This ensures that fan vibrations from the instruments on the shelves do not reach the table surface. They are made from formed and welded steel with a black powder coat finish. Leveling feet and casters are included for easy mobility and stability on uneven floors. Hanging shelves for extra storage space are optional. OptoSigma offers a wide selection overhead shelves and shelf accessories.
