    Product Structure Information

    GMT Optical Table consists of Breadboard、Isolator and Support. More structure details are as below: 

    ♦ Based on the structure of breadboard, could be separated to Honeycomb type and Welding type

       Honeycomb type

    • The breadboard should have high natural resonance frequency and good damping properties. The resonance frequency is related to the stiffness and quality of the object, reducing the quality or increasing the stiffness will increase the resonance frequency. Conversely, increasing the quality or decreasing the stiffness will reduce the resonance frequency.

    • The balance of quality and stiffness is a very important concept in the design of optical table, because they can make the resonance of optical table reach low amplitude and high frequency. Obviously, this can only be achieved by increasing the stiffness of the breadboard. Because if you increase the quality in the same proportion, the resonance will not change. In order to increase the resonant frequency, stiffness must be maximized while minimizing quality. So we chose a honeycomb breadboard with high stiffness and low quality.

    • Honeycomb breadboard has a structure with good damping performance, high stiffness and low quality characteristics, the honeycomb is made of steel bars that have been precisely crimped, and then bonded together with a high tensile strength epoxy adhesive to effectively resist bending.

    • The addition of the isolation cup can effectively prevent the liquid from entering the honeycomb cavity and ensure the use in a clean environment.

      Welding type

    • Welding plate construction

    • Top surface grinding,flatness 1 / 600 x 600 mm,roughness 0.8 μm

    • Economical

    ♦ Vibration isolators are divided into rubber isolators, precision damping isolators and air-floating isolators

      Rubber Isolator

    • Using the natural characteristics of elastic materials to make shock isolation elements of a certain shape and size, it can also be regarded as a simple extruded shock isolator.
    • Suitable for occasions with low seismic isolation requirements.

      Precision Damping Isolator

    • Radial stiffness is 2-3 times of axial stiffness, with good lateral stability.

    • Rubber is subjected to both compressive and shear forces.

    • The natural frequency is as low as 11Hz, which is suitable for occasions with certain seismic isolation requirements, such as general spectroscopy and multimode fiber coupling.

     Air-Floating Isolator

    • Double-layer air chamber design reduces the stiffness of the air-floating isolator.

    • Orifice airflow restriction will dampen oscillating motion between ground and platform, reducing adjustment time.


    ♦ The support legs are divided into one-piece welded support legs and independent support legs

      One-piece Welded Support Leg

    • Strong rigidity and good stability.

      Independent Support Legs

    • There is no connecting rod, which can obtain better vibration isolation effect, which is convenient for placement and transportation.

    ♦ High precision height control valve

    • The air-floating isolation optical platform can automatically level the entire platform system with high precision and speed. The adjustment lever can be rotated 360 degrees, and the repeated positioning accuracy is ± 3 mm.
