Abstract
The utility model relates to a spectrometer multi-flat inclined mirror, which is characterized in that: 24 flat mirrors are distributed on an outer circumferential side surface of a cylinder, an angle between a normal of the flat mirrors and the bottom surface of the cylinder is varied from 0, -12, 0, +12 and 0, the angle difference between any two adjacent flat mirrors is 2 on the vertical direction, when the normal of the flat mirror faces is inclined upwards relatively to the bottom surface of the cylinder, + is marked, and when the normal of the flat mirror faces is inclined downwards relatively to the bottom surface of the cylinder, - is marked, an obliquity parameter is marked on the upper end surface of the cylinder, the spectrometer multi-flat inclined mirror is arranged on a carrier platform when in adjustment, the carrier platform and the spectrometer multi-flat inclined mirror are slowly rotated, the bright + symbol which is reflected by a flat mirror can be across the field coverage of an ocular, once when the bright + symbol is seen, the adjustment direction can be judged according to the obliquity parameter of the flat mirror, and an optical axis of a self-aligning telescope can be easily adjusted to be vertical to a central axis of an instrument through a both-half adjusting method.
Description
Technical field
The utility model relates to a kind of fast adjuster of spectrometer.
Background technology
Spectrometer is a kind of precision optical instrument, also is the foundation structure of many optical instruments simultaneously.Many colleges and universities science and engineering MED all will be done the adjusting and the application experiment of spectrometer, wherein the 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 the range of telescope, learn through the reality test, the 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 the range estimation coarse adjustment, bright " ten " word of flat mirror reflects resembles and just can not appear on the film viewing screen, can't see bright " ten " word and resembles and just can't finish the adjusting work of telescope optic axis perpendicular to centre.Use the people of spectrometer for first study, 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 bright " ten " word that the somebody spends the time of whole laboratory also to can not find flat mirror reflects resembles.
Summary of the invention
Telescope optic axis and level crossing normal angle are bigger than normal when estimating coarse adjustment in order to overcome, be difficult to find the difficulty of bright " ten " word elephant in the eyepiece field of view, the utility model has designed the many flat inclined mirrors of a kind of spectrometer, can be easy to find in eyepiece field of view bright " ten " word to resemble.
The many flat inclined mirrors of described spectrometer, be 24 level crossings that on the excircle side of a cylinder, distributing, level crossing normal and cylinder bottom surface angle are 0,-12,0, change between+12 and 0 degree, any two adjacent level crossings differential seat angle on above-below direction each other are 2 degree, level crossing minute surface normal is tilted to subscript "+" number with respect to the cylinder bottom surface, otherwise mark "-" number, dip angle parameter is labeled on the cylinder upper surface, when estimating the coarse adjustment telescope optic axis perpendicular to the centre axle, mix up the telescope focal length behind the infinite distance, the many flat inclined mirrors of described spectrometer are placed on the objective table, many flat inclined mirrors central shaft overlaps substantially with the objective table central shaft, slowly rotate objective table, the many flat inclined mirrors of spectrometer and then rotate, because adjacent two level crossings differ 2 degree on above-below direction, less than the subtended angle of eyepiece with respect to the centre axle, be bound to streak eyepiece field of view so always there is bright " ten " word of a flat mirror reflects to resemble in the many flat inclined mirrors of spectrometer, even one time excessive velocities is not seen, slow down rotational speed and just can see that bright " ten " word resembles, in case seeing bright " ten " word resembles, just can judge the direction of adjusting according to the inclined-plane parameter of this level crossing, utilization " half and half adjusting method " just can regulate the auto-collimator optical axis very like a cork perpendicular to the centre axle.
Advantage of the present utility model is that many flat inclined mirrors help the operator to be easy to find bright " ten " word to resemble, and can judge the adjusting direction according to the dip angle parameter of reflecting surface, finish telescope optic axis smoothly to the vertical adjusting of centre axle, and and then finish this experiment smoothly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the many flat inclined mirrors of spectrometer.
Among the 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, processing 24 width on the excircle side of cylinder (5) equates, the uniform sulculus of spacing, paste a level crossing in each sulculus, level crossing (1)---(2)---in (3) each level crossing minute surface normal be followed successively by 0 with respect to the angle of cylinder bottom surface, + 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 cylinder (5) upper surface of level crossing correspondence, "+" number expression level crossing minute surface normal with respect to the cylinder bottom surface upwards, "-" number then expression is downwards.
Claims (2)
1. many flat inclined mirrors of spectrometer, it is characterized in that 24 level crossings that on the excircle side of a cylinder, distributing, level crossing normal and cylinder bottom surface angle 0 ,-12,0 ,+change between 12 and 0 degree, any two adjacent level crossings differential seat angle on above-below direction each other are 2 degree, level crossing minute surface normal is tilted to subscript "+" number with respect to the cylinder bottom surface, otherwise mark "-" number, dip angle parameter is labeled on the cylinder upper surface.
2. the many flat inclined mirrors of spectrometer according to claim 1 is characterized in that the many flat inclined mirrors of spectrometer are placed on the objective table, and many flat inclined mirrors central shaft overlaps substantially with the objective table central shaft.
