Passive Isolation Breadboard Support Frames![]()
Passive Isolation Casters Available ![]() Please Wait ![]() Features
These passive isolation frame presents an ideal, cost-effective, vibration isolation solution for optical breadboards up to 48" x 72" (1200 mm x 1800 mm) in size. The frames are available for either standard loads of 24 to 260 kg (50 to 570 lb) or heavy-duty loads of 135 to 700 kg (300 to 1540 lb) and are supplied with a frame height of 800 mm (31.5”) from stock. Frames with a height of 700 mm (27.6") are available as make to order items. The passive system is based on four independent, air-mounted, passive vibration isolators. The isolators can be inflated by a simple foot pump. With a vertical resonance frequency of 3.5 Hz, these isolators are an ideal solution for general photonic applications in a typical lab environment. Passive isolation is particularly effective for instruments with a high center of gravity, providing the stability and stiffness required to result in rapid attenuation of vibrational disturbances. Please follow the instructions outlined in the user guide so that the isolators are neither overinflated nor underinflated. Each isolator consists of a cylindrical reinforced rubber air mount in the top of a steel leg, as shown in the drawing to the right. The pressure of the isolator can be adjusted by admitting or releasing air through a standard Schrader valve on the side of each isolator. The tables below list the frame suitable for each breadboard size. For breadboard sizes which do not have a stock or make to order passive frame, we offer two options. Thorlabs offers a larger size selection of rigid breadboard support frames, and a passive isolator upgrade kit to retrofit a rigid frame with passive isolators. Custom sizes may also be available upon request; please contact Tech Support with your requirements and for pricing. Please see the Vibration Isolation Tutorial for more information the design of our products and the theory of vibration isolation and damping.
Transmissibility PlotA vibration isolation system is subjected to continuous vibrational impulses from the laboratory floor. These vibrations may be caused by large machinery within the building or even by wind- or traffic-excited building resonances (swaying). Transmissibility is a measure of the isolators efficiency at damping out these vibrations and is defined as the ratio of the amplitude of the transmitted vibration to that of the forcing vibration.
Selecting a Vibration SystemThorlabs offers three types of breadboard support systems: Active Isolation, Passive Isolation and a rigid support system. The Active and the Passive isolation systems are both based on compressed air, providing vibration isolation in frequencies above 2Hz and 10Hz (respectively) making them ideal systems for demanding photonic experiments or for work in a noisy environment. In addition, Thorlabs also offers rigid support systems with no vibration isolation for less demanding applications which require only breadboard isolation. The table below compares the isolation performance of our different isolation systems.
Vibration IsolationVibration isolation is needed to isolate between noises originating around the workstation and breadboard surface. Such vibrations may result from machinery in the building such as elevators or compressors, pedestrians, building vibrations and nearby street traffic. The role of the vibration system is to dampen, both horizontally and vertically, the noises generated by the surrounding environment. Such noises are typically in the range of 10-100 Hz. the table below depicts common vibration sources:

These standard passive vibration-isolation breadboard supports feature a frame height of 800 mm (31.5"). Our stock frames fit metric breadboards up to 900 mm x 1200 mm (or imperial breadboards up to 36" x 48"). These frames can support loads up to 260 kg (570 lb). The passive isolators are a static isolation system and do not require a constant air supply; therefore, our foot pump can be used to inflate the isolators. Click on More [+] on the table below to see the frame suitable for each breadboard size. For breadboard sizes that do not have a stock passive frame, it is possible to purchase a rigid breadboard support frame and a passive isolator upgrade kit and retrofit the rigid frame with passive isolators. Custom sizes may also be available upon request; please contact Tech Support with your requirements and for pricing.

These casters are designed to permit easy relocation of the breadboard support frames, without removal of equipment or disassembly of the system. They are ideal for positioning the frames within tight spaces. Each caster rides on a non-marring wheel for smooth and quiet operation. Supplied as a set of four. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
