TMC’s CleanTop® Optical Tops and Breadboards provide the ultimate in optical top performance. Unmatched in the industry, these products combines the smallest cell-size and highest core density with the unique CleanTop® design, all-steel construction, and the unsurpassed levels of structural damping. 

Note: Optical tops and leg support systems are sold separately

Performance Levels

  • Research Grade 784 SeriesProvides 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 LaserTable-Base™ support, a hybrid air/piezoelectric, 2-stage vibration cancellation system.
  • Scientific Grade 783 SeriesScientific Grade has the same design features as Research Grade including core size and density, CleanTop cups, and all-steel construction with reduced damping. Peak compliance levels for Scientific Grade damping exceed peak compliance levels of Research Grade damping by a factor of 4.
  • Laboratory Grade 781 SeriesProvides an economical performance level for the least sensitive applications in less severe floor vibration environments. The Laboratory Grade is appropriate for general lab applications where the primary requirement is for a rigid, flat mounting surface.
