The New VIBe™ vibration isolation platform consists of a baseplate, 3 or 4 IB vibration isolators and corresponding mounting brackets ( VIB-BRKT ). The products are compact, effective and easy-to-use platforms that significantly reduces vibrations from disturbing sensitive instruments such as microscopes, inspection or analysis equipment. All VIBe™ units feature a black powder-coated steel plate and patented mechanical IB series isolators that provide both vertical and horizontal vibration isolation, there are no air lines, compressors or other accessories needed to provide effective isolation performance.
Baseplate in VIBe™ Platform
The baseplate in VIBe™ platform is available in four standard shapes, two rectangular ( VIB-1218 , VIB-1824 ,) and two triangular ( VIB-G001 , VIB-G002 ), that have been designed to satisfy the widest range of application needs. The two rectangular baseplates come in 12”x18” and 18”x24” sizes and can be equipped with isolator bearings to support payloads from 5lbs to over 350lbs. The triangular models have been designed specifically to accommodate a large assortment of microscope footprints from all leading manufacturers. Special shapes and sizes are also available on request.

Vibration Isolators in VIBe™ Platform
VIBe™ Series IB isolator bearings are mechanical isolators available in discrete payload ranges as identified by their part number. For very light instruments, the IB-1018 isolates total payloads from 10-18 lbs per bearing and for heavy instruments the IB-50100 isolates total payloads from 50-100 lbs per bearing. IB Isolators are passive and mechanical and do not require air hoses, maintenance or supporting hardware.
In total, six models of IB bearings that effectively cover a load range from 10-100 lbs isolator are available. This allows users to configure the proper size platform and position bearings in the required locations on a baseplate to support and isolate their instrument, even if the load is not uniform, as in the case of microscopes which are typically heavier in the rear by as much as 50%.
Each bearing is a self-contained unit that provides both vertical and horizontal isolation for that specified load range. The isolators feature a 6.7Hz vertical resonance frequency that begins isolating at 9Hz and a horizontal resonance of 6.3Hz with isolation beginning at 8Hz. This is sufficient performance to eliminate 85% of vibration noise seen within typical laboratories. The IB bearings attach to the VIBe baseplate via specially designed brackets that feature a threaded aperture to allow leveling adjustment of the platform.

Selecting the proper VIBe components for your application
The VIBe™ Series provides hundreds of configurations depending on the size and shape of your payload and custom variations are also available. A typical installation would consist of a baseplate, 3 or 4 IB isolation bearings and their respective mounting brackets. Integrating the Newport VIBe™ is accomplished in three easy steps:
The first step in selecting the proper components is determining the size and weight of the instrument being isolated. It is also recommended to determine the weight distribution of the instrument so that the proper load capacity bearings can be selected at each support point.
Next, select the proper VIBe™ baseplate to properly support the entire footprint of your instrument. If your instrument has a high center of gravity or a moving payload you may need to select an oversized baseplate and use four IB bearings to improve stability.
After the baseplate size and shape are selected, determine which IB bearings are needed to properly support and isolate your instrument. For example, consider an instrument that weighs 125 lbs, is a uniform load, has a low CG and has a footprint of 16”x20”. The best choice for a baseplate is the VIB-1824 which weighs 46lbs. To support this total 171 lb load you would need four bearings with a minimum capacity of 42.8 lbs each. If there is more than one IB bearing available in the required range choose the IB for which the payload falls closest to the middle of the range. In this example both the IB-2947 and the IB-3775 would work. If the load for the application is not expected to increase the proper choice would be the IB-2947 .
For microscope applications it is important to understand the weight distribution in the front and rear to make the proper bearing selection. Consider a microscope that weighs 100 lbs with a weight distribution of 40% in the front and 60% in the rear and best fits onto a VIB-G002 that weighs 21.6lbs. A three bearing arrangement would require one 50.8 lb capacity bearing in the front and two 35.4 lb capacity bearings in the rear. The best choice for the rear bearings would be the IB-2340 and the front would be a IB-3775 .
