Optical platforms are widely used in electronics, optics, precision machinery manufacturing, and other fields, as well as precision experimental instruments and equipment vibration isolation in other machinery industries. So, what is its structure and composition, how to identify its quality?
What is the structural composition of the optical platform?
The basic components of the standard optical platform include top plate; bottom plate; side face finishing; side plate; honeycomb core; sealed cup, etc.
Its accessories are:
1. Support frame
The optical platform includes a rigid, non-vibration isolation support frame, a passive vibration isolation support frame, and an active automatic leveling support frame;
2. Other accessories
Other accessories of the optical platform include shelves, mounts, under-desk shelves, vibration isolation accessories, optical platform accessories that can be installed with poles, adjustable optical climbing frame mounts, earthquake suppression, optical breadboard covers, shading materials, and magnetism Slices, and so on.
How to identify the quality of the optical platform
Precise optical experiments rely on reliable positioning stability. Vibration in and near the working area can cause relative movement between optical components, resulting in unacceptable deviations.
These deviations will cause: the acquired image is blurred, the spot deviation causes the inaccuracy of data collection, etc. Therefore, the choice of the optical platform plays a vital role in improving the accuracy of the experiment.
From the structural point of view, the optical platform is mainly divided into two parts: the table and the support, so the vibration isolation performance of the optical platform depends on the vibration isolation performance of the table itself and the support. Generally speaking, the vibration isolation of the optical platform is achieved through three aspects.
Generally speaking, the performance of air-floating vibration isolation supports is better than that of damped vibration isolation supports. Some vibration isolation supports with excellent performance can reduce the external vibration (common 10 ~ 200Hz) by one to two orders of magnitude. It requires that the table has certain rigidity and is relatively light (hard weight ratio), so that the table can effectively reduce the amplitude of resonance.
A high-quality optical platform not only requires high-precision machinery and equipment for processing but also requires high-tech precision testing methods and testing instruments to ensure that only a high-quality optical platform can ensure the normal progress of high-precision scientific experiments and scientific research.
