"Take a look at the Minus K stands. They use only springs."
Well, almost. They use combination of springs and "flexures" (beams under compression) - a technically complex isolation technique called "negative stiffness."
Once upon a time, around 8 years ago, Newport Corp. sold the Sub-Hertz Platform - also a negative stiffness isolator with Resonant Frequency circa 0.5 Hz.
