Abstract
The invention relates to a multi-obliquity mirror for a spectrometer, wherein 24 plane mirrors are distributed on an outer periphery side of a cylinder, intersection angles between normals of the plane mirrors and the cylinder bottom face range between 0, -12, 0, +12 and 0 degrees, an angle difference between any two adjacent plane mirrors in upward and downward directions is 2 degrees, + is marked when the normals of the plane mirrors are inclined upward relative to the cylinder bottom, otherwise, - is marked, an inclination parameter is marked on an end face of the cylinder, during adjustment, the multi-obliquity mirror for the spectrometer is placed on an object stage, the object stage and the multi-obliquity mirror for the spectrometer are slowly rotated, once a bright cross image reflected by one of the plane mirrors occurs in an ocular viewing field and is seen, an adjustment direction is judged according to the inclination parameter of the plane mirror, and an optical axis of a self-alignment telescope can be easily adjusted to be perpendicular to a central axis of an apparatus via a half-and-half adjustment method.
Description
Technical field
The present invention relates to a kind of fast adjuster of spectrometer.
Background technology
Spectrometer is a kind of precision optical instrument, is also the foundation structure of many optical instruments simultaneously.Many colleges and universities science and engineering MED all will be done adjusting and the application experiment of spectrometer, wherein auto-collimator optical axis is very difficult perpendicular to the adjusting of centre axle, reason is that auto-collimator sends " ten " word light bright " ten " word that flat mirror reflects is returned on objective table and often resembles and do not appear in range of telescope, through reality test, learn, auto-collimator eyepiece is about 2.5 degree with respect to the subtended angle of centre axle, as long as the angle of auto-collimator eyepiece optical axis and level crossing normal is greater than 1.25 degree during range estimation coarse adjustment, bright " ten " word of flat mirror reflects resembles and just there will not be on film viewing screen, can't see bright " ten " word resembles and just cannot complete telescope optic axis perpendicular to the adjusting work of centre.For first study, use the people of spectrometer, range estimation guarantees that it is difficult especially that the angle of auto-collimator eyepiece optical axis and level crossing normal is not more than 1.25 degree during coarse adjustment, and somebody spends bright " ten " word that the time of whole laboratory also can not find flat mirror reflects to resemble.
Summary of the invention
While estimating coarse adjustment in order to overcome, telescope optic axis and level crossing normal angle are bigger than normal, are difficult to find the difficulty of bright " ten " word elephant in eyepiece field of view, and the present invention has designed a kind of spectrometer multi-flat inclined mirror, can be easy to find bright " ten " word to resemble in eyepiece field of view.
Described spectrometer multi-flat inclined mirror, 24 level crossings that distributing on the excircle side of a cylinder, level crossing normal and cylinder bottom surface angle are 0,-12, 0, between+12 and 0 degree, change, any two the adjacent level crossings each other differential seat angle on above-below direction are 2 degree, level crossing minute surface normal with respect to cylinder inclined bottom surface to subscript "+" number, otherwise mark "-" number, dip angle parameter is labeled on cylinder upper surface, when range estimation coarse adjustment telescope optic axis is perpendicular to centre axle, mix up telescope focal length behind infinite distance, described spectrometer multi-flat inclined mirror is placed on objective table, many flat inclined mirrors central shaft overlaps substantially with objective table central shaft, slowly rotate objective table, spectrometer multi-flat inclined mirror and then rotates, because adjacent two level crossings differ 2 degree on above-below direction, be less than eyepiece with respect to the subtended angle of centre axle, so always there is bright " ten " word of a flat mirror reflects to resemble in spectrometer multi-flat inclined mirror, be bound to streak eyepiece field of view, even if one time excessive velocities is not seen, slow down rotational speed and just can see that bright " ten " word resembles, once see that bright " ten " word resembles, according to the inclined-plane parameter of this level crossing, just can judge the direction of adjusting, use " half and half adjusting method " just can regulate very like a cork auto-collimator optical axis perpendicular to centre axle.
The invention has the advantages that many flat inclined mirrors help operators to be easy to find bright " ten " word to resemble, and can judge adjusting direction according to the dip angle parameter of reflecting surface, complete smoothly telescope optic axis to the vertical adjusting of centre axle, and and then complete smoothly this experiment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the structural representation of spectrometer multi-flat inclined mirror.
In figure, 1,0 degree plane mirror, 2 ,+12 degree plane mirrors, 3,0 degree plane mirror, 4 ,-12 degree plane mirrors, 5, cylinder, 6, dip angle parameter.
Specific embodiments
In Fig. 1, on the excircle side of cylinder (5), processing 24 width equates, the uniform sulculus of spacing, in each sulculus, paste a level crossing, level crossing (1)---(2)---in (3) each level crossing minute surface normal with respect to the angle of cylinder bottom surface, be followed successively by 0, + 2, + 4, + 6, + 8, + 10, + 12, + 10, + 8, + 6, + 4, + 2 and 0 degree, level crossing (3)---(4)---in (1) angle of each level crossing minute surface normal and cylinder bottom surface be followed successively by 0,-2,-4,-6,-8,-10,-12,-10,-8,-6,-4,-2 and 0 degree, dip angle parameter (6) is labeled on the cylinder that level crossing is corresponding (5) upper surface, "+" number expression level crossing minute surface normal with respect to cylinder bottom surface upwards, "-" number represents downwards.
Claims (2)
1. a spectrometer multi-flat inclined mirror, it is characterized in that 24 level crossings that distributing on the excircle side of a cylinder, level crossing normal and cylinder bottom surface angle change 0 ,-12,0, between+12 and 0 degree, any two the adjacent level crossings each other differential seat angle on above-below direction are 2 degree, level crossing minute surface normal with respect to cylinder inclined bottom surface to subscript "+" number, otherwise mark "-" number, dip angle parameter is labeled on cylinder upper surface.
2. spectrometer multi-flat inclined mirror according to claim 1, is characterized in that spectrometer multi-flat inclined mirror is placed on objective table, and many flat inclined mirrors central shaft overlaps substantially with objective table central shaft.
