The ClassOne™ CleanTop^® Optical Top design is an extension of the original CleanTop, adapted for cleanrooms.

It is Class 100 cleanroom compatible with an all-stainless steel construction (stainless steel cups optional).

Features:

• Individual cups under each tapped hole are airtight
• 3/16 in. (5 mm) thick top skin
• Stainless steel top, bottom, sides
• Cleanroom-compatible design and packaging
• Two levels of fixed damping available:
  
  • Maximum Dry Damping
  • Standard Dry Damping

How to Order:

• Choose the size and thickness of the top that you need from either the Maximum Damping Chart or Standard Damping Chart below.
• You will need to specify the available Hole Pattern / Threads and /or Laser Ports. Click here to see the Hole Pattern / Laser Port Suffix Chart.
• Contact TMC for purchasing and shipping information.
