Chapter 1 Safety 1.1 Safety Information For the continuing safety of the operators of this equipment, and the protection of the equipment itself, the operator should take note of the Warnings, Cautions and Notes throughout this handbook and, where visible, on the product itself. The following safety symbols may be used throughout the handbook and on the equipment itself. Shock Warning Given when there is a risk of injury from electrical shock. Warning Given when there is a risk of injury to users.
Chapter 2 Operation 2.1 General Description Thorlabs passive isolators are designed to remove floor vibrations in the critical 10Hz to 50Hz frequency range. The passive air mount design is ideal for most general optical table uses, providing low frequency isolation coupled with excellent stability in both horizontal and vertical directions. The thick wall construction assures maximum safety and overload protection with an economical design.

Chapter 3 3.2.3 Mounting the Table on the Isolators 1) Raise the table on a fork-lift truck, ensuring that the fork distance is set such that the forks can pass between the isolators when the table is lowered into position – See Fig. 3.2. forks distance between isolators Fig. 3.2 Distance between forks 2) Manoeuvre the fork-lift truck until the table is over the isolators. Carefully lower the table until it is around 20mm above the isolators. 3) Lower the table onto the isolators.
Passive Isolating Optical Table Supports 5) Repeat items (2) to (4) until all four isolators have a gap of 63 mm (2.48”) between the top of the cylinder and the underside of the table – see Fig. 3.4. standard load heavy load 63 mm (2.48") 63 mm (2.48") correctly inflated under inflated over inflated Fig. 3.4 Correct inflation of passive isolators 6) Check that the table top is level. If the floor is uneven, the gap between the table and each isolator may not be the same.
Chapter 3 3.4 System Stability The location and height of a load placed on a table top can dramatically affect the stability of the table system. To ensure optimum effectiveness of the isolators, it is important to avoid any instability due to the system centre of mass being misplaced.
Chapter 4 Joined Systems The location and pneumatic connections for a joined system will depend on the configuration of the system. Some typical examples are shown below. Please contact your local tech support office for more details. 4.1 Smaller Systems Although single tables require four isolators, smaller joined systems may require only six rather than eight isolators. The number of isolators required will depend upon the joiner configuration and the size of the tables.
4.2 Larger Systems Depending on the configuration of the joiner, larger systems may require eight or more isolators as shown below. Fig. 4.
