Optical platforms, also known as optical breadboards, optical tabletops, scientific desktops, and experimental platforms, provide a level and stable tabletop. Generally, platforms need vibration isolation and other measures to ensure that they are not disturbed by external factors and allow scientific experiments to proceed normally. At present, there are two main categories: active and passive. There are two types of passive rubber and air flotation.

Introduction
The optical platform pursues level, and the entire table is extremely flat when first processed. After that, the table is placed on the four airbags connected to ensure the table is level. The table is covered with engineering threaded holes arranged in a square. These holes and corresponding screws can be used to fix the optical components. In this way, when you complete the construction of the optical equipment, the system will basically not be changed by external disturbances. Even if the table is pressed, it will automatically return to the level due to the airbag.

application
The optical platform is widely used in the fields of optics, electronics, precision machinery manufacturing, metallurgy, aerospace, aviation, marine, precision chemical and non-destructive testing, as well as other key devices for precision test instruments and equipment vibration isolation in the machinery industry.

Main composition
The basic components of a standard optical platform include: 1. a top plate; 2. a bottom plate; 3. side-finished and attached faces; 4. side plates; 5. a honeycomb core; 6. a sealed cup.

Construction of steel
High-quality platforms and breadboards shall have an all-steel structure, including 5 mm thick top and bottom plates, and precision-machined welded steel honeycomb cores with a thickness of 0.25 mm. The honeycomb core is made by precise laminating tools, and its geometric spacing is guaranteed by welding flat gaskets. The honeycomb core structure in the platform and breadboard extends from the top plate to the bottom plate without a transition layer in the middle, thereby forming a stronger and more stable platform product.

Thermal stability
The key to thermal stability is a symmetrical, uniform steel structure in each axis. Steel parts have similar elongation and shrinkage during heat exchange, and can maintain good flatness during temperature changes. The steel honeycomb core structure extends from the top plate to the bottom plate, and there is no plastic or aluminum leakage management structure in the middle, so it will not reduce the overall stiffness of the platform or introduce a higher thermal expansion coefficient. We use steel side panels instead of wooden boards, which eliminates the environmental instability caused by humidity.

Main accessories
Support

The optical platform includes a rigid, vibration-isolating support frame, a passive vibration-isolation support frame, and an active self-leveling support frame.
