Optical Tables

Optical Tables

Optical Table and Breadboard products are designed to provide a large, vibration isolated and damped work surface from which to conduct optical experiments.  An optical table consists of two main items: a support and an optical tabletop or breadboard.  The support can be in the form of a frame with casters or as four individual cylindrical legs.  The supports can be either elastomeric (rigid) with nominal vibration isolation or pneumatic, which provides the best isolation from floor vibrations.  The tabletop has a matrix of 1/4-20 or M6 threaded holes on the surface and is constructed with a steel honeycomb structure to make it stiff, but with minimal mass. The vibration control provided by optical tables is frequently used in applications such as microscopy, metrology, optical fiber alignment, interferometry, or wherever optical experiments are done.  Optical tables can be found in just about any laser lab but also support bio-medical, life sciences, astronomy, metrology, and semiconductor industries.  OptoSigma offers a wide selection of optical table sizes from stock, desk-type workstations and desktop isolators and shelf accessories.   If one of our many catalog tables does not meet your requirements, send us a request for a custom table.

Do you know all the sources of vibration in a laboratory?


vibration
  • Ground Vibrations: Caused by foot traffic, vehicles, HVAC systems, building movement, and even distant construction.
  • Acoustic Noise: Includes sounds that exert force on equipment, such as airflow from fans or HVAC ducts.
  • Ground Vibrations: Refers to vibrations applied directly to the table or equipment from cables, motors, or moving components (e.g., linear stages).
