Vibration Isolation Baseplate
IRVINE, Calif., March 8, 2011 — Newport Corp. has introduced a tabletop vibration isolation platform designed for sensitive instrumentation and microscopes. The VIBe vibration isolation baseplate is a compact and easy-to-use platform that reduces vibrations that can disturb sensitive instruments.
Available in four standard shapes, two rectangular and two triangular, it features a black powder-coated steel plate and patented mechanical isolators that provide both vertical and horizontal vibration isolation. No air lines, compressors or other accessories are required.
Fundamental to the device are the IB isolator bearings, which are available in discrete payload ranges. The company offers six models of IB bearings that cover a load range from 10 to 100 lb, enabling users to configure the proper size platform and bearings in the required locations on the baseplate to support and isolate their instrument, even if the load is not uniform.
The isolators feature a 6.7-Hz vertical resonance frequency that begins isolating at 9 Hz, and a horizontal resonance of 6.2 Hz with isolation beginning at 9 Hz. This eliminates more than 85% of vibration noise seen within typical laboratories. The bearings attach to the VIBe baseplate using specially designed brackets that feature a threaded aperture to allow leveling adjustment of the baseplate.
The two rectangular platforms come in 12 × 18- and 18 × 24-in. sizes and can be equipped with isolator bearings to support payloads from 5 to >350 lb. The triangular models have been designed to accommodate a large assortment of microscope footprints from all leading manufacturers. Custom shapes and sizes also are available upon request.
The maintenance-free baseplate is suitable for use in isolation of microscopes, rheometers, inspection and analysis instrumentation, and sample preparation stations. The company also offers customized baseplates and individual IB isolators for easy integration into OEM systems.
