Multi-degree-of-freedom adjustable optical vibration reduction platform

Abstract

The invention provides an adjustable optical vibration reduction platform with multiple degrees of freedom, comprising: a mounting base; an intermediate body connected to the mounting base through a vibration absorber; a wedge-type adjustment body slidingly connected to the intermediate body; a workbench , is arranged on the intermediate body, and its lower end surface fits and contacts with the upper end surface of the wedge iron adjustment body; a lifting adjustment component; a horizontal adjustment component. The multi-degree-of-freedom adjustable optical vibration reduction platform of the present invention can be used alone or in combination, and can be applied to complex optical path coupling alignment, installation and positioning occasions where high precision is required, and the vibration excitation spectrum characteristics of the operating environment are not clear or frequently changed. ;Especially suitable for optical path coupling alignment and positioning of complex optical systems with a large number of optical components, complex coupling optical paths, long transmission distances, combined use of multiple optical platforms, frequent changes of installation and use locations, and large differences in environmental vibration excitation spectrum .

[0002] The existing optical platforms commonly used for optical components and optical path layout and installation are usually installed on the air bearing vibration reduction system, and the air bearing vibration reduction system is usually designed for fixed vibration reduction and vibration isolation frequency according to the vibration excitation spectrum characteristics of the use environment , each support point of the air bearing support and vibration reduction system has a certain real-time leveling function through air pressure adjustment, and is mostly suitable for a single stand-alone use; when the number of optical components is large, the coupling optical path is complex, the transmission distance is long, and multiple platforms are required When in use, the adjustment process is more complicated, and the relative stability between platforms is poor

In addition, the optical platform in the prior art is not suitable for the use of complex optical systems that require frequent changes in installation and use locations where the vibration excitation spectrum is uncertain, and the long-term relative stability of multiple platforms is poor when used jointly
