Abstract

The utility model belongs to the technical field of optical instruments and is a fast regulator for a spectrometer which can be used for regulating various spectrometers. The fast regulator for a spectrometer is characterized in that the front end and the back end of the fast regulator are respectively provided with a front frame and a back frame which can surround and can be fixed on the cylinder of a spectroscope. The fast regulator can be made into various shapes according to the actual demand. The utility model has the advantages of simple structure, convenient installation and operation, low cost and high reliability. The regulating efficiency of the spectrometer can be raised. The time can be saved. The fast regulator is convenient to be manufactured in large.

Description

Fast regulator for spectrometer

The utility model belongs to the optical instrument technical field.

Spectrometer is the important instrument in the optical measurement, widespread use teaching, research and production.Spectrometer must be regulated before measurement, and adjustment process is very loaded down with trivial details and time-consuming.Current control method is to be reflected into green cross (adjusting the picture of cross hair) in the telescope by the workplace that the telescope on the spectrometer is sought beam splitter.Because the telescopical ken is very little, the green cross visibility that the workplace of beam splitter reflects is very little, therefore will find in telescope that green cross is very difficult.Must regulate the inclination angle of the telescopical elevation angle and platform in order to seek green cross, and this adjusting is blindly to carry out fully.In order to overcome the adjusting difficulty of spectrometer, many people inquire into the control method of spectrometer.The article that " Physical Experiment " publishes the Zhang Zhi of Ji'nan University hero in June, 1986 " is tried to make a comment the Principles of Regulation and the control method of a spectrometer " literary composition and publish the king of Shaanxi Normal University in October, 1988 and deposit justice " mirror of spectrometer is seen and looked like a fast regulating method " literary composition outward the adjusting problem of spectrometer has been discussed, but all be limited to improvement, all do not provide a kind of effective and cheap apparatus and solve this difficult problem original method.

The purpose of this utility model provides a kind of velocity modulation device of spectrometer, improves the adjusting efficient of spectrometer.

The utility model is made of following several parts: (1) rear and front end has the surface plate of frame, the front bezel right side has opening, can be loaded on the telescope tube and be screwed, back frame divides two halves up and down, first frame and surface plate fuse, second frame can link fixing with screw and first frame, before and after the line at two frame centers should be within surface plate or certain plane parallel with surface plate, when this device is loaded on the lens barrel, lens barrel passes two frames, the line of centres of two frames and lens barrel optical axis coincidence.(2) be contained in the miniature bulb of surface plate downside, as light source; (3) a certain end of light transmitting fiber (should constitute by many) is loaded on around the miniature bulb, is used to receive the light that miniature bulb sends, and the other end places on the front bezel leading surface, constitutes the luminous point group (or luminescence zonal texture) around the frame center.Make frame surface plate is the level of state during installation, make telescope optic axis within certain plane of surface plate or certain plane parallel with the surface plate surface around lens barrel.

Principle of the present utility model is to seek target (green cross) during Spectromenter Adjustment in the mirror to change mirror into and seek target (picture that contains the luminous point group of the cross of having chance with) outward, has overcome blindness, has improved the observability of target.

The key of Spectromenter Adjustment is to make telescopical optical axis vertical with the public rotating shaft of instrument, promptly vertical with the workplace of beam splitter on the platform, when using this device to carry out the beam split adjusting, can be with the left side of arbitrary workplace alignment telescope object lens of beam splitter on the platform, the observer looks to beam splitter along the telescope left side, then can see the luminous point group on the front bezel or the picture of luminous zone, the picture of the crosshair on the telescopical graticule is the edge cross, inevitable within luminous point group or light belt picture, then with screw and telescopical pitching screw under the 1/2 method adjusting platform, the horizontal hair of edge cross is just in time fallen within on the surface plate in the surface, the observer looks along the surface plate upper surface, be as the criterion with the horizontal hair that can see the edge cross, then telescope or platform are rotated slightly around the spectrometer rotating shaft, then from telescope, must see the edge cross,, then do to regulate getting final product slightly with 1/2 method if the horizontal hair of edge cross and adjustment cross hair not exclusively overlap.Each transparent surface to used beam splitter is all so regulated, and then can make telescopical optical axis reach vertical with each workplace of beam splitter rapidly.

Advantage of the present utility model is that (1) changes that to seek target in the mirror be that mirror is sought target outward and is convenient to find target, overcome blindness: (2) change searching edge cross for looking for the picture of luminous point group or luminescence zonal texture earlier, and the edge cross must be in the picture of luminous point group or luminescence zonal texture; (3) simple in structure, be convenient to install and use, improved work efficiency, saved the time.(4) with low cost, dependable performance is convenient to produce in batches; (5) can with the supporting use of existing spectrometer, also can with the supporting use of spectrometer of old various model specifications, make things convenient for the user.

The utility model can be made into various moulding as required, but its principle is constant.

Accompanying drawing is an embodiment of the present utility model.Accompanying drawing 1 is a cut-open view of the present utility model, and accompanying drawing 2 is vertical views of the present utility model.1 is front bezel among the figure, and 2 is light transmitting fiber, and 3 is miniature bulb, and 4 is the back frame, and 5 is screw rod, and 6 is nut, and 7 is luminous point, and 8 is surface plate.

Claims

1, a kind of spectrometer speed adjuster, the front-end and back-end that it is characterized in that this speed adjuster respectively have one can be on the beam split lens barrel around fixing front bezel [1] and back frame [4], front bezel [1] and back frame [4] are linked from the side by 1 or two surface plates [8], and the line of centres of front bezel [1] and back frame [4] overlaps with telescope optic axis, around the frame central distribution a group luminous point or luminous zone [7] is arranged on the forward position of front bezel [1].

2,, it is characterized in that the line of centres of described front bezel (1) and back frame (4) should be in a certain surface of surface plate (8) or a certain plane parallel with the surface by claim 1 described spectrometer speed adjuster.
