Description
Technical field
The utility model is a kind of optical rotary table, particularly a kind of optical rotary table that is suitable for two groups of optical components around rotation of common axle synchronous backward and the adjusting of anglec of rotation difference energy trace.
Background technology
Optical rotary table is the adjusting gear a kind of commonly used that in Experiments of Optics and the optical instrument optical component is carried out angular adjustment.Optical component is fixed on the platen of optical rotary table, and the rotation by optical rotary table realizes its angular adjustment.
Formerly (P.969-1032) the Newport Resource, Motion Control:Manual RotationStages and Motorized Rotation Stages.2003 have described the one dimensional optical universal stage of multiple model to technology [1].These one dimensional optical universal stages are with its personalization and diversity, have satisfied a lot of request for utilizations and are widely used.But an one dimensional optical universal stage can only be regulated separately one group of optical component.Need be in same plane during reverse rotation when two groups of optical components, must adopt two one dimensional optical universal stages to make up and could realize.Two one dimensional optical universal stages are used in combination, and regulate the anglec of rotation difference of two groups of optical components that are fixed thereon easily.The trace of the anglec of rotation difference of two groups of optical components is regulated the error analysis experiment that can be used for photoelectric measurement.Because two one dimensional optical universal stages rotate around separately turning axle respectively, can't satisfy two groups of optical components and rotate around common axis of rotation.And two different drive sources of one dimensional optical universal stages employing, be difficult to realize the synchronous rotation of two groups of optical components.It is necessary that two groups of optical components are rotated in some Experiments of Optics and the optical instrument around the common axis of rotation synchronous backward, just requires Laser Devices and photoelectric detector to rotate around the common axis of rotation synchronous backward when employing is scanned into the firing angle method as surface plasma resonance laboratory.
Formerly technology [2] (Su Datu chief editor. optical testing technology. publishing house of Beijing Institute of Technology, Beijing, 1996, P.86) a kind of manual optical rotary table has been described.This optical rotary table can be realized two groups of optical components around the common axis of rotation reverse rotation, but this optical rotary table can not be realized the synchronous rotation of two groups of optical components.
Formerly technology [3] (development of Deng Wen and .JC-l type precision goniometer. photoelectric project, Vol.17, No.1,1990, P.35-48) a kind of optical rotary table has been described.This optical rotary table can realize that two groups of optical components are around the common axis of rotation reverse rotation.But this optical rotary table can not change the anglec of rotation difference of two groups of optical components that are fixed thereon when rotation synchronously.If will change the anglec of rotation difference that is fixed in two groups of optical components on the optical rotary table, optical rotary table just can not rotate synchronously.
These two kinds of optical rotary tables described in technology [2] and [3] formerly, because two rotations platens and optical components are all directly supported by rotary axis, but rotation platen load capacity is heavy in order to make, bulky optical component also guarantees steadily rotation, the structural design more complicated of these two optical rotary tables, and bulky.
