Abstract
The invention relates to a reflect light adjusting method of a spectrometer collimator, comprising the following steps of: on the basis of well adjustment on a telescope of the spectrometer, lighting a light source, moving a spectrometer to make the slit end of the collimator align to the light source, rotating the telescope on a position forming an angle of 90 DEG with the collimator, and placing a plane mirror on an object stage so that lamp light from the slit and the collimator are reflected to the telescope by the plane mirror, observing the state of the slit light in the collimator by an operator through the telescope and stretching out hands to a collimator slit device to adjust the width and the focal length of the slit as well as the horizontal and vertical positions of parallel light. From a geometrical relationship, it is known that when the telescope and the collimator are in an angle of 90 DEG, the distance from the eye lens end of the telescope to the end of the collimator slit device is only 0.707 time that when the telescope and the collimator are in a straight line, i.e. the distance from the eye lens end of the telescope to the end of the collimator slit device is reduced by 30 percent, and the operator can stretch out hands to easily adjust the width and the focal length of the slit of the collimator slit device as well as the horizontal and vertical positions of parallel light.
Description
Affiliated field
The present invention relates to the focal length, slit width, the level of parallel rays, the control method of vertical position of spectrometer parallel light tube.
Background technology
Spectrometer is a kind of precision optics surveying instrument, the major function of parallel light tube is that source light is become the suitable directional light of a beam width, this distance that just need regulate the width of slit arrangement and slit and lens equals the focal length of lens just, mixes up level, the vertical position of parallel rays simultaneously.Because when parallel light tube and telescope are in alignment, telescope ocular to the distance of parallel light tube slit arrangement for farthest, before operator's eyes are in telescope ocular, feel that arm is shorter relatively when stretching out one's hand level, the vertical position of width, focal length and the parallel rays of regulating the parallel light tube slit arrangement, operate very difficult, even be difficult to mix up level, the vertical position of slit width, focal length and parallel rays, thereby work quality and progress have greatly been influenced.
Summary of the invention
For solve because of telescope ocular and parallel light tube slit arrangement distance relative far away, operator's arm is short relatively partially and regulate the level of width, focal length and the parallel rays of parallel light tube slit arrangement, the problem of vertical position difficulty, the present invention has designed a kind of reflect light adjusting method of spectrometer collimator, through experimental results show that the level that can satisfactorily resolve spectrometer parallel light tube slit width, focal length and parallel rays, the problem that vertical position is regulated difficulty repeatedly.
It is relative far away with parallel light tube slit arrangement distance that the present invention solves the spectrometer telescope ocular, operator's arm is lacked and the width of adjusting parallel light tube slit arrangement relatively partially, the level of focal length and parallel rays, the technical scheme of vertical position difficult problem is, at first regulate telescopical eyepiece, the focal length of object lens, and make telescope optic axis perpendicular to the centre rotating shaft, on the basis of carrying out the spectrometer telescope adjustment, point bright light source mercury lamp or sodium vapor lamp, mobile spectrometer is by parallel light tube slit ends alignment light source, telescope is forwarded to the position that becomes 90 degree with parallel light tube, on objective table, put a plane mirror, the light of coming from the irradiation of slit and parallel light tube is reflexed to the telescope through plane mirror, the operator observes the state of slit light in the parallel light tube by telescope, and stretch out one's hand parallel light tube slit arrangement place and regulate slit width, the level of focal length and parallel rays, vertical position, from geometric relationship as can be known, when telescope becomes 90 to spend with parallel light tube, telescope ocular end 0.707 times when the distance of parallel light tube slit arrangement end has only telescope and parallel light tube to be in line, the distance that is both has reduced 30%, the operator just stretch out one's hand can easy adjustment parallel light tube slit arrangement slit width, the level of focal length and parallel rays, vertical position.After level, the vertical position of slit width, focal length, parallel rays all regulate, take off plane mirror, telescope is rotated back into directional light tubular axis extensions direction, just can begin to have carried out follow-up test work.
The invention has the beneficial effects as follows the plane mirror that utilizes spectrometer itself to have, not increasing any parts, only is to rotate telescope to becoming 90 degree positions just can effectively solve the relative weak point of operator's arm with parallel light tube and making the level of parallel light tube slit width, focal length, parallel rays, the problem that vertical position is regulated difficulty.

Specific embodiments
At first regulate the eyepiece (8) of telescope (7) and the focal length of object lens, and make telescope (7) optical axis perpendicular to the centre rotating shaft, these relevant telescopical adjustings are that the spectrometer user should accomplish at first.On this basis, reflect light adjusting method of spectrometer collimator of the present invention is, point bright light source (1), mobile spectrometer makes slit arrangement (2) alignment light source (1) of parallel light tube (3), telescope (7) is forwarded to the position that becomes 90 degree with parallel light tube (3), on objective table (4) upper surface, put a plane mirror (5), regulate the orientation of plane mirror (5), light from slit and parallel light tube is reflexed in the telescope (7), operator's eyes place telescope ocular (8) preceding, the slit arrangement (2) of parallel light tube (3) of stretching out one's hand is located to regulate, because the distance when telescope (7) becomes 90 to spend with parallel light tube (3) only for both when in alignment distance 70%, the operator regulates the width of slit arrangement, the level of focal length and parallel rays, vertical position is no longer felt because of the short partially difficulty of arm.
Claims (1)
1. reflect light adjusting method of spectrometer collimator, it is characterized in that on the basis of carrying out the spectrometer telescope adjustment, the point bright light source, mobile spectrometer is by parallel light tube slit ends alignment light source, telescope is forwarded to the position that becomes 90 degree with parallel light tube, on objective table, put a plane mirror, the light of coming from the irradiation of slit and parallel light tube is reflexed to the telescope through plane mirror, the operator observes the state of slit light in the parallel light tube by telescope, and stretch out one's hand parallel light tube slit arrangement place and regulate slit width, the level of focal length and parallel rays, vertical position, from geometric relationship as can be known, when telescope becomes 90 to spend with parallel light tube, telescope ocular end 0.707 times when the distance of parallel light tube slit arrangement end has only telescope and parallel light tube to be in line, the distance that is both has reduced 30%, and any operator can not feel that arm is lacked partially and the adjusting difficulty.
