Claims19
A suspension system for an instrument having a frame and vertically supported mounting platform, comprising:
- at least three vertically disposed sway rods each fixedly attached at a first end to said frame and pivotally and slidably coupled to said vertically supported mounting platform such that a second end of said sway rods is substantially free to translate in a horizontal plane defined by a pair of orthogonal axes and said mounting platform is substantially free to translate along a vertical axis normal to the horizontal plane;
- first means coupled to said frame for limiting translation of said second ends of said sway rods in said horizontal plane;
- second means for limiting the translation of said mounting platform along said vertical axis;
- third means for damping horizontal translation of said sway rods;
- and
- fourth means for damping vertical translation of said mounting platform.
