TMC 71x47x4 inch optical table with base

Product Description

TMC 71″ x 47″ x 4″ CleanTop Research Grade Optical Table with 32″ Tall Support Base – Precision Vibration-Isolated Workstation

This used TMC (Technical Manufacturing Corporation) optical table system represents the gold standard in precision vibration control for demanding research applications. The 71″ x 47″ x 4″ all-steel honeycomb top delivers exceptional rigidity and damping, while the 32″ tall base provides robust support at an ergonomic working height.

TMC is the world leader in optical table technology, and their CleanTop® Research Grade tables are specified for the most demanding applications including interferometry, holography, ultra-fast lasers, and environments with severe floor vibration . This table combines the highest core density and smallest honeycomb cell size available, ensuring unmatched structural performance .

The CleanTop® Advantage

TMC’s patented CleanTop® design offers several critical benefits that set it apart from competitors :

All-Steel Construction

• No particle board sidewalls or plastic layers between the top skin and honeycomb core

• Assures maximum strength and structural integrity

• All components share the same coefficient of thermal expansion for optimal thermal stability

Smallest Core Cell Size, Highest Core Density

• Average cell size of 0.5 in² is at least 50% smaller than competing designs

• Achieved through cylindrical CleanTop cups (not conical like plastic layer designs)

• Ensures highest stiffness and greatest core-to-skin bonding contact area

Superior Spill Protection

• Individual CleanTop cups are epoxy-bonded under each tapped hole

• Liquid spills are contained on the surface and cannot reach the honeycomb core

• The core remains completely clean and dry with no residual thread-cutting oils to out-gas

Steel-to-Steel Bonding

• Only two bonding layers: top skin to core and core to bottom skin

• Imitations require a third bonding layer which weakens the structure

Structural Damping

TMC’s Research Grade tables utilize advanced broadband dry damping technology, which is superior to “tuned” damping methods used by competitors :

• Broadband Damping: Dissipates energy across the entire frequency range of interest, addressing primary, secondary, and higher resonant frequencies

• No Oil Dampers: Eliminates risk of oil leakage and performance changes over time

• Performance Guarantee: TMC guarantees maximum compliance levels (measured in micro-inches per pound) for their tables, with Research Grade providing the highest damping performance available

Applications

This Research Grade optical table is recommended for the most demanding applications :

• Interferometry – Michelson, Twyman-Green, and Fizeau interferometers

• Holography – requiring extreme stability for fringe stability

• Ultra-Fast Lasers – Ti:Sapphire and fiber laser systems

• Quantum Optics – single-photon experiments and atomic physics

• Confocal Microscopy – high-resolution imaging requiring sub-nanometer stability

• Spectroscopy – Raman, fluorescence, and absorption measurements

• Nanotechnology – probe-based and optical characterization

Condition

EXCELLENT – WELL-MAINTAINED 
TOP SURFACE: clean, minimal cosmetic scratches, minimal rust
TAPPED HOLES: Clean, no damage
SIDEWALLS: Intact, no dents
BASE: Stable, level
CLEANTOP CUPS: Intact, fully functional

⚠ INSTALLATION NOTE: This is a heavy system requiring proper floor support. The 32″ base height provides a standard working surface when combined with the 4″ table top (total working height ~36″). Ensure adequate floor loading capacity before installation.
