 Product Briefing Outline: Newport's "ND60 NewDamp" isolator
provides economical vibration-isolation support for lowload
applications, such as breadboards, optical rails, laser systems, and
Newport's line of workstations. Fabricated from a highly engineered
form of U-16 polyurethane, these new products deliver up to five times
better damping than other commercial elastomeric isolators. In
addition, the use of a novel (multiple-cone) geometry yields isolation
performance that is virtually load-independent, unlike systems based on
softer materials.
Problem: A remarkable property of NewDamp isolators is their ability to
quickly attenuate the transient motions, thereby reducing the settling
time of the equipment after the stage movements or other disturbances.
Solution: NewDamp isolators are ideal for testing and manufacturing
applications that do not require the lowfrequency isolation bandwidth
of pneumatic or active isolation systems. These include wafer
inspection and positioning systems, and precision electronic
manufacturing. For production environments, NewDamp isolators offer
enhanced convenience and ease-of-use, because they do not need any
electronic circuitry, air hoses, or other supporting hardware.
Moreover, their short settling time makes these products ideal for use
in high throughput situations. In addition, the U-16 material is fully
cleanroom compatible and even meets NASA spacecraft outgassing
specifications.
Applications: The ND60 isolators are based on conical elastic elements
designed for low load applications. ND50's supports loads up to 17lbs
(8 kg). That do not require the low-frequency isolation bandwidth of
pneumatic or active isolation systems such as optical rails & laser
systems.
Platform: NewDamp isolators are available in a variety of standard and
custom designs. In addition, NewDamp elastomers are also available as
elastic elements, for incorporation into OEM vibrationisolations
systems.
Availability: July 2004 onwards.
