Abstract
The utility model discloses a spectrometer quick-adjusting device mainly composed of a large bifacial reflector, a semiconductor laser, a web and a press plate, etc. The large bifacial reflector is positioned on the objective table of the spectrometer, whose diameter of the light-reflecting surface is 2 to 3 cm larger than the distance between the laser beam and the telescope optical axis; the web is fastened to the telescope ring by a plurality of screws; the semiconductor laser is arranged on the V-shaped groove of the web and fastened by the press plate and a plurality of nuts. When the device is arranged, make sure the laser beam is parallel with the telescope optical axis. Led by a visible laser bean, firstly, a mutual perpendicularity can be made between the laser beam, the telescope optical axis and the spectrometer centre shaft (comprising a large reflector surface). Based on the process, the model is realized that the telescope is focalized to the infinite distance in the case that the bright ''crisscross'' is appeared on the screen only by changing the distance between the eye lens, the field lens and the reticle. The rest of the adjustment of the spectrometer is simpler.
Description
Affiliated technical field
The utility model belongs to the optical instrument application.
Background technology
Spectrometer is a kind of instrument of precision measurement angle, claims to divide photogoniometer again.It is many optical instruments commonly used, and as the element of instruments such as spectrophotometer, chromatograph, monochromator, purposes is very extensive.Simultaneously, spectrometer also is one of underlying instrument of university's optical physics experiment." adjusting of spectrometer and use " is the optical physics experiment that many college students must be done.By this experiment, the student not only can be used to optical principle test with the understanding of intensification to principle, and can exercise student ' correctly use optical instrument, regulates the manipulative ability of testing aspects such as light path.
In the adjusting of spectrometer, " adjusting telescope focal length infinite distance " and " it is vertical with the spectrometer central rotating shaft to regulate telescope optic axis " two steps are difficult points, in experiment, the student spends the plenty of time and energy all is difficult for finishing voluntarily, have in addition spend the whole laboratory time and also regulate bad.The main cause that causes " regulating telescope focal length infinite distance " difficulty is plane minute surface and the telescope optic axis out of plumb on the objective table, there is not the student of operating optical instrument experience to be difficult to guarantee that by range estimation vertical error is very little, even thereby accommodated to the infinite distance, bright " ten " word picture does not appear in the visual field yet.Cause " it is vertical with the spectrometer central rotating shaft to regulate telescope optic axis " difficult main cause to be still plane minute surface and the telescope optic axis out of plumb on the objective table, the student has spent bright " ten " word picture that a lot of time just mix up, and treats that objective table drives to have can not find after level crossing turns over 180 degree.
Summary of the invention
In order to overcome the adjusting difficulty of " regulating telescope focal length infinite distance " and " telescope optic axis is vertical with the spectrometer central rotating shaft ", the utility model provides a kind of fast adjuster of spectrometer, the adjusting of the adjusting of " telescope optic axis is vertical mutually with the spectrometer central rotating shaft " and " telescope focal length infinite distance " is become be easy to.
The utility model solves above-mentioned " regulating telescope focal length infinite distance " and the technical scheme of " it is vertical with the spectrometer central rotating shaft to regulate telescope optic axis " two big crucial difficult problems is, a described fast adjuster of spectrometer is installed on spectrometer, and it mainly is made up of big two-sided reflective mirror, semiconductor laser, web joint and pressing plate etc.Big two-sided reflective mirror places on the spectrometer objective table, its reflective surface diameter should be bigger 2 to 3 centimetres than the distance of laser beam and telescope optic axis, web joint is fastened on screw on one's body the telescope tube, and semiconductor laser installing is also fastening with pressing plate and nut on web joint " V " type groove.Install and guarantee that laser beam is parallel with telescope optic axis.When regulating spectrometer, light semiconductor laser, allow a reflective surface of the big two-sided reflective mirror of laser beam directive, rotate big two-sided reflective mirror and make flare trend semiconductor laser lightening hole, fit adjustment (normally half and half adjusting method) by objective table and telescope adjustment screw, make flare get back to the lightening hole of semiconductor laser, rotate after objective table drives big two-sided reflective mirror and turn over 180 degree, possible hot spot is not at the lightening hole of semiconductor laser, make hot spot get back to the semiconductor laser lightening hole once more by half and half adjusting method, so repeatedly several times, moving 180 degree of objective table revolution, the flare of next arrogant two-sided reflective mirror is always got back to the lightening hole of semiconductor laser, this just shows that semiconductor laser beam and centre rotation axis are orthogonal, because of semiconductor laser beam is parallel to telescope optic axis, thereby just realized that also telescope optic axis and spectrometer central rotating shaft are orthogonal.Keep big two-sided reflective mirror and telescopical relative position motionless subsequently, turn off semiconductor laser, light the little illuminating lamp in the spectrometer, the adjusting eyepiece makes black " ten " word line and " ten " word cross hair is clear greatly, unclamp the eyepiece stalk lock-screw again, change eyepiece, object lens are with respect to the position of graticule, because telescope optic axis is perpendicular to big two-sided reflective mirror, as long as black " ten " are when word line is in the focal plane, bright " ten " word line will very clearly appear at the top of eyepiece field of view, its horizontal line also will overlap with the last horizontal line of big " ten " word cross hair and (also may cause bright " ten " word not exclusively to overlap as the last horizontal line of horizontal line and big " ten " meaning of word silk because of semiconductor laser beam and telescope optic axis are not exclusively parallel, only need finely tune and get final product), this has just shown that the telescopical infinite distance function that accommodates to realizes.In sum because telescope optic axis and the mutually perpendicular adjusting of spectrometer central rotating shaft carry out under visible semiconductor laser beam guiding, thereby very directly perceived, be easy to; Because telescope optic axis and centre rotating shaft are orthogonal, and big two-sided reflective mirror is also vertical with telescope optic axis, accommodating to the infinite distance only is the relative position that changes object lens and graticule and eyepiece, as long as black " ten " are when word line is in the focal plane, picture promptly bright " ten " word of its black " ten " word line looks like to be bound to appear at upper horizontal line place, visual field, and the operator is easy to see.Even accommodated to the infinite distance before having avoided, because of bright " ten " word picture does not appear in the visual field, the phenomenon that the operator also blindly adjusts disorderly.Finished this most difficult operation of two steps, other adjustings of spectrometer are just simple.
The beneficial effects of the utility model are that device is simple, adjusting is directly perceived, processing ease, can make student image understand the Principles of Regulation of spectrometer intuitively, and the good spectrometer of quick adjustment.
