The structure of optical platform and how to distinguish its quality

- Oct 30, 2019-

Optical platform is widely used in electronic, optical, precision machinery manufacturing and other fields, as well as other mechanical industries of precision experimental instruments, equipment vibration isolation, then, what is its structure composition, how to identify its quality, about these aspects, you can not understand, the following is sorted out for you, please see the following for you What's coming!

What is the structure of the optical platform

The basic components of the standard optical platform include: top plate; bottom plate; side surface finishing; side plate; honeycomb core; sealing cup, etc.

Its accessories are:

1. Support frame

The optical platform includes rigid and non vibration isolation support frame, passive vibration isolation support frame and active automatic leveling support frame.

2. Other accessories

Other accessories of optical platform also include shelf, mounting base, under table shelf, vibration isolation accessories, optical platform accessories for mounting support bar, adjustable optical climbing frame mounting base, seismic suppression, optical bread plate cover, light shielding material, magnetic sheet, etc.

How to distinguish the quality of optical platform

Precise optical experiments depend on reliable positioning stability. Vibration in and near the working area will cause relative motion between optical components, resulting in unacceptable offset.

These offsets will lead to the following phenomena: the collected image is blurry, the facula offset makes it impossible to collect data or the data collection is inaccurate, etc., so the selection of optical platform plays an important role in improving the experimental accuracy.

From the structural point of view, the optical platform is mainly divided into two parts: the table and the bracket, so the vibration isolation performance of the optical platform depends on the vibration isolation performance of the table itself and the bracket. Generally speaking, the vibration isolation of the optical platform is realized through three aspects.

Generally speaking, the performance of the air floating vibration isolation bracket is better than that of the damping vibration isolation bracket. Some excellent vibration isolation brackets can reduce the external vibration (common 10-200hz) by one to two orders of magnitude. The table top is required to be rigid and light (hard weight ratio), which can effectively reduce the amplitude of resonance.
