Executive Summary :

It is envisaged to develop a Negative Stiffness Mechanism Based passive vibration isolation platform. The platform is intended to be used in attenuating ground vibrations for a LASER based optical experiment. The isolator must be capable of attenuating ground vibrations above 0.7 Hz, in all six degrees of freedom. Natural frequency of the system shall be 0.5Hz or below. Mode of operation shall be passive.
