Profile: Micro Control Instruments Ltd. specializes in providing optical and electrical measurement instruments. Anti vibration optical tables feature input signals from heavy traffic or construction travel through the ground to the building. The foundations of the building and the ground surrounding them, act as a series of springs and dampers, mitigating transmission of vibration at some frequencies, and increasing it at others. The frequencies of vibration transmitted in this way tend to be most important between 5Hz and 300Hz.
