TMC's new 2,000-watt laser machining center coupled with our capacity to punch, drill, shear, form, and weld steel made this custom rectangular through-hole inclusion seen on this table.
Research Grade CleanTop® provides the ultimate in optical top performance.
Unmatched in the industry, Research Grade performance combines the smallest cell-size and highest core density with the unique CleanTop® design, all-steel construction, and the highest level of structural damping commercially available.
Research Grade CleanTops are recommended for the most demanding applications including interferometers, holography, and ultra-fast lasers, as well as the most severe floor vibration environments.
For the best overall vibration control, consider combining this top with a STACIS® iX support, a hybrid air/piezoelectric, 2-stage vibration cancellation system.
