Thorlabs' Anti-Vibration Optical Table Workstations provide an excellent platform for the most demanding applications. Below are links to all the different sized active-air (self-leveling) isolation systems we offer. Please note that a 700 mm tall frame (i.e., one from the second row of options) should be chosen for use with a 210 mm (8.3") thick optical table, while a 600 mm tall frame (i.e., one from the first row of options) should be chosen to accommodate a 310 mm (12.2") thick optical table. This maintains a constant working surface height of 910 mm (36") regardless of the thickness of table chosen.
