Abstract
The utility model discloses a spectrometer used in experiments. The spectrometer comprises a collimator, a dial, an objective table, and a telescope. The telescope comprises an objective lens cone and an eyepiece sleeve. The eyepiece sleeve is provided with a reticle. The reticle is provided with crosshairs. The spectrometer is characterized in that grooves are disposed on positions of the crosshairs on the reticle. Lengths of the grooves are the same with lengths of the crosshairs. Widths of the grooves are the same with widths of the crosshairs. A fluorescent material is filled in the grooves. The spectrometer is advantaged in that the grooves which are equal in width and length with original crosshairs are disposed on positions of the original crosshairs on the reticle, and fluorescent powders or fluorescent paint is added in the groove, that is the fluorescent crosshairs formed by the fluorescent powders or the fluorescent paint replace the original crosshairs. When the spectrometer is specifically used, the reticle is just needed to be illuminated for a short time by using a flashlight when an experiment begins, and long-time clear and bright fluorescent crosshairs are obtained, so that an experimenter can rapidly and accurately complete related adjustment and perform observation.
Description
Technical field
The utility model relates to a kind of spectrometer, especially relates to a kind of experiment spectrometer.
Background technology
Spectrometer is a kind of precision optics surveying instrument, relates generally to the observation of optical phenomena and the measurement of respective angles.Common spectrometer mainly is made up of telescope, parallel light tube, objective table, index dial four parts.Graticule on the telescope plays an important role when measuring, and obtaining accurately, the result relates generally to following three steps: 1) adjust graticule and be located on the focal plane of object lens; 2) when regulating " telescope optic axis is vertical with the spectrometer rotating shaft ", bright cross picture is overlapped with the crosshair on graticule top; 3) measuring the vertical cross hair with graticule of time institute's viewing ray will align fully.And graticule is illuminated, and the cross hair on the graticule is high-visible to be the basic assurance of finishing above operation.
The general extensive employing Abel telescope of spectrometer commonly used.In Abel's telescope, light source can effectively illuminate the hollow out cross of graticule below, thereby obtain clear bright cross curve through the reflection of illuminating prism.But for the top of graticule, then can not form effective illumination, be difficult to the cross hair of clear view to the graticule, the experiment of simultaneously relevant spectrometer is carried out in the darker laboratory of light mostly, and dim environment more is unfavorable for observing the cross hair on the graticule.In practical operation, all to hand torch in telescopical object lens the place ahead, for graticule provides illumination, such operation has not only increased the complexity of experiment, and because the instability of hand-held torch is run into testing sample easily, tend to cause the failure of an experiment.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of apparent experiment spectrometer of crosshair that can make on the graticule.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of experiment spectrometer, comprise parallel light tube, index dial, objective table and telescope, described telescope comprises objective tube and eyepiece stalk, described eyepiece stalk is provided with graticule, described graticule is provided with crosshair, and the position of crosshair is provided with groove on the described graticule, and the length of described groove is identical with the length of described crosshair, the width of described groove is identical with the width of described crosshair, is filled with fluorescent material in the described groove.
Described fluorescent material is fluorescent powder.
Described fluorescent material is fluorescent paint.
Described fluorescent paint is the green fluorescence lacquer.
Compared with prior art, advantage of the present utility model is: depict in the position of the former crosshair of graticule and the wide isometric groove of former spider silk thread, and in groove, add fluorescent powder or fluorescent paint, namely the fluorescence crosshair that constitutes with fluorescent powder or fluorescent paint replaces original crosshair, during concrete the use, only need when the experiment beginning, to illuminate graticule with the torch short time, can obtain long-time clear bright fluorescence crosshair, relevantly adjust and observe thereby the experimenter is finished rapidly and accurately.

Embodiment
Describe in further detail below in conjunction with the utility model of accompanying drawing embodiment:
Embodiment one: as shown in the figure, a kind of experiment spectrometer, comprise parallel light tube, index dial, objective table and telescope, wherein, telescope comprises objective tube 1 and eyepiece stalk 2, eyepiece stalk 2 is provided with graticule 3, graticule 3 is provided with crosshair 31, and the position of crosshair 31 is provided with groove 32 on the graticule 3, and the length of this groove 32 is identical with the length of crosshair 31, the width of groove 32 is identical with the width of crosshair 31, is filled with fluorescent material in the groove 32.
In this specific embodiment, fluorescent material is fluorescent powder.
Embodiment two: other parts are identical with embodiment one, and its difference is that fluorescent material is fluorescent paint.
In this specific embodiment, fluorescent paint is the green fluorescence lacquer.
