But if you are not sure how much damping your application requires or to prepare for potential changes to your experimental requirements or lab environment, the upgradeable ST-UT2 Series combines Newport’s fine tuned damping with IQ damping. ST-UT2 Series SmartTables tables are field upgradeable to ST Series performance. When the IQ dampers are not installed, the ST-UT2 table provides performance equivalent to the RS2000 Series table. As your application requirements become more stringent, the ST-UT2 table can be field upgraded to SmartTable performance levels by installing an IQ-200-UG upgrade kit. There is no need to dismantle your experiment in order to upgrade the table. Once upgraded, the ST-UT will provide a dramatically quieter table surface, resulting in high quality imaging, improved long term stability, faster settling times and the ability to make measurements that previously required the quietest lab environments. The upgraded STUT2 SmartTable also allows users to monitor tabletop vibrations through built in vibration sensors that provide real time feedback on the vibration state of the table. • Field upgradeable to ST Series SmartTable performance • Selectively eliminate torsional and bending table modes • Damped work surface elminates skin resonance • Honeycomb cells for a lighter, stiffer table with better dynamic rigidity • Triple core interface increases point loading capability Specifications Working Surface 400 Series ferromagnetic stainless steel 3/16 in. (4.8 mm) thick with integrated damping layer Surface Flatness [in. (mm)] ±0.004 (±0.1), over 2 ft. (600 mm) square Core Design Trussed honeycomb, vertically bonded closed cell construction, 0.010 in. (0.25 mm) Steel sheet materials, 0.030 in. (0.76 mm) Triple core interface Tuned Damping Narrowband hydraulic vibration absorbers Broadband Damping Constrained layer core, damped working surface and composite edge finish Mounting Holes 1/4-20 holes on 1 in. grid (M6-1.0 holes on 25 mm grid), 0.5 in. borders (12.5 mm borders) Hole/Core Sealing Easy clean conical cup 0.75 in. (19 mm) deep, Non-corrosive high impact polymer material Typical Table Performance Values RS 2000 Series Maximum Dynamic Deflection Coefficient 0.8 x 10-3 Maximum Relative Motion Value [in. (mm)]* <8.0 x 10-9 (<2.0 x 10-7) Deflection Under Load [in. (mm)]= <5.0 x 10-5 (<1.3 x 10-3) Note: All typical performance values are for 12 in. thick tables. *Calculated and verified by interferometric testing in relatively quiet lab; table on isolators. =Calculated and verified for a 250 lb (114 kg) load placed in the center of a 12 in. table. ST-UT2 Series comes standard with 1/4-20 holes on 1 in. grid; for M6 metric holes on 25 mm grid add the prefix “M-”. Vibration isolators are sold separately. 10 100 1 .10 1 3 .10 7 1 .10 6 1 .10 5 1 .10 4 1 .10 3 Active damping ON Active damping OFF Rigid Frequency (Hz) Compliance (in/lb) ST-UT2 Series compliance curve. The table resonances are dramatically reduced when damping is enables. This compliance curve is shown for an 8" thick table. 50 100 150 200 250 300 350 400 450 0 0.5 1 1.5 2 Active damping ON Active damping OFF Frequency, (Hz) Displacement (nm) The vibration spectrum of a ST-UT2 Series Smart Table with iQ damping is shown. When the iQ damping system is activated the motion on the table is minimized. iQ damping eliminates the resonances of the table, particularty in the sensitive100-300 Hz range. Additionally, when comparing the ST-UT2 vibration spectrum to the ST vibration spectrum notice that the amplitude is much less in the ST-UT2 series due to the tuned damping.
