The improved collimator facilitates adjustment of a spectrometer, makes the spectrometer more user friendly, and improves the adjusting accuracy and experiment efficiency of the spectrometer.
Description
Technical field
The invention belongs to optical experiment instrument field, relate to a kind of spectrometer parts, be specially a kind of modified form collimator.
Background technology
Collimator is a critical piece of spectrometer, before experiment, it is necessary to collimator is adjusted, in order to produce the directional light that experiment is required.Needing to go to telescope the position just to collimator during adjustment, then limit is observed by telescope, while stretch out one's hand the position and width that regulate collimator tail end slit, until observing from telescope clearly, till the slit image of suitable width.Due to collimator and telescope in alignment time, telescope ocular is farthest to the distance of collimator tail end slit, and the arm of experimenter often reaches slit, is difficult to accomplish that observation limit, limit regulates, thereby result in the adjustment difficulty of collimator, affect the accuracy of conventional efficient and adjustment.
Summary of the invention
The purpose of the present invention, is the collimator improving spectrometer, develops a kind of convenient modified form collimator regulated.
In order to solve above-mentioned technical problem, the present invention by the following technical solutions:
A kind of modified form collimator, including pipe shaft, the collecting lens being fixed on pipe shaft one end, it is plugged on the slit arrangement of the pipe shaft other end, slit arrangement includes slit plate and the slit sleeve of slit plate fixed connection, slit sleeve activity is inserted in pipe shaft and is fixed by the sleeve lock-screw of being located on pipe shaft and pipe shaft, is provided with broad-adjustable slit in slit plate；Described pipe shaft is " L " shape hollow, cylindrical tube, is sequentially connected with is constituted by straight tube A, right-angle elbow pipe, straight tube B, fixes one piece of plane mirror becoming 135 degree of angles with tube wall in right-angle elbow pipe.
Right-angle elbow pipe and straight tube A are for being rotatably connected, and right-angle elbow pipe can rotate around the axis of straight tube A, to coordinate the light source being located at diverse location.
The invention has the beneficial effects as follows: owing to collimator pipe shaft is " L " shape, shorten the slit arrangement distance to telescope ocular, be conducive to experimenter limit to be observed by telescope, limit regulates slit location and width, facilitate the adjustment of spectrometer, be conducive to embodying the human oriented design of experimental apparatus, improve accuracy and the conventional efficient of Spectromenter Adjustment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.

In figure: 1. pipe shaft, 2. collecting lens, 3. slit plate, 4. slit sleeve, 5. slit width adjusting knob, 6. plane mirror, 7. sleeve lock-screw, 8. spectrometer, 9. light source, 10. telescope, 11. straight tube A, 12. right-angle elbow pipes, 13. straight tube B.
Detailed description of the invention
As shown in Figure 1, the pipe shaft 1 of collimator is " L " shape hollow, cylindrical tube, it is sequentially connected with is constituted by straight tube A11, right-angle elbow pipe 12, straight tube B13, the base of straight tube A11 and spectrometer 8 is fixed, fixing one piece of plane mirror 6 becoming 135 degree of angles with tube wall in right-angle elbow pipe 12, collecting lens 2 is fixed on the port of straight tube A11.Slit arrangement includes slit plate 3 and the slit sleeve 4 of slit plate 3 fixed connection, slit sleeve 4 activity is inserted in straight tube B13 and is fixed with straight tube B13 by sleeve lock-screw 7, being provided with slit in slit plate 3, slit width is regulated by the slit width adjusting knob 5 being located at slit plate 3 side.
As shown in Figure 2, telescope 10 on spectrometer 8 is gone to the position just to straight tube A11, the light that light source 9 sends passes sequentially through slit plate 3, slit sleeve 4 and straight tube B13, plane mirror 6 in directive right-angle elbow pipe 12, it is reflected into straight tube A11 through plane mirror 6, then through directive telescope 10 after collecting lens 2, experimenter limit is observed by telescope 10, while save position and the slit width adjusting knob 5 of slit sleeve 4 with hand adjustment, until observing clearly from telescope 10, till the slit image of suitable width, now the slit in slit plate 3 is placed exactly on the focal plane of collecting lens 2.
Right-angle elbow pipe 12 and straight tube A11 are for being rotatably connected, and right-angle elbow pipe 12 can rotate around the axis of straight tube A11, in order to coordinate the light source 9 being located at diverse location.In Fig. 2, light source 9 is located at the left side of spectrometer 8, is suitable for left hand and regulates collimator.Light source 9 also can be located at the right side of spectrometer 8, is suitable for the right hand and regulates collimator.Light source 9 also can be located at the top of spectrometer 8, thus embody spectrometer human oriented design and experiment in light source position arrange motility.
