Minus K vibration isolation systems can be made vacuum compatible so they can be used right inside vacuum chambers. In addition to their superior vibration isolation performance, this offers other advantages of much lower payload weights, more compact systems, and eliminates problems associated with vacuum chamber feed-throughs. See, for example, Spitzer Space Telescope Case Study.
Our vibration isolation systems have also been used to support
entire vacuum chambers. This offers the advantages of more
standard designs and lower costs in some cases.
