        品牌: TMC

        • 詳細信息

        賽默飛世爾定制版SEM主動隔振平臺SEM Base LP


        SEM-Base LP is a custom, low profile version of our standard SEM-Base active piezoelectric vibration cancellation platform. SEM-Base LP is easier to install, provides outstanding performance, and is ergonomically optimized. The compact design facilitates installation without lifting the Scanning Electron Microscope (SEM) column with anything other than the SEM’s built-in leveling feet. And, once installed, the SEM’s height above the floor does not increase. SEM-Base LP incorporates our unique STACIS piezo technology and has the same vibration cancellation performance as our industry-standard SEM-Base VI. SEM-Base LP includes casters and is designed specifically to integrate with many Thermo Fisher Scientific (formerly FEI) tools.

        The SEM-Base Advantage

        Hard-Mount Technology – SEM-Base is compatible with internal SEM vibration control systems and aggressively mitigates low frequency floor vibration starting at 0.6 Hz.


        Active Inertial Vibration Cancellation – SEM-Base uses high sensitivity, low frequency inertial velocity sensors to achieve high levels of vibration attenuation, even on quiet floors. 


        Serial Design with Piezoelectric Technology – The unique serial design and proprietary highforce piezoelectric technology results in a wide active bandwidth from 0.6 Hz to 150 Hz and unmatched, inertial active vibration cancellation with 90% reduction starting at 2 Hz.
