Abstract
The utility model discloses a kind of reading microscope for Newton's rings experiment, comprise base, vertical with base connect vertical rod, the microscope be movably fixed in vertical rod, also comprise article carrying platform, light source, illumination ring, the upper surface of base is located in article carrying platform activity, light source is located at chassis interior, and illumination ring set is located on micro objective.The utility model avoids in experiment the inconvenience regulating light source and object of observation position etc., not only can from reflected light direction, but also can to observe from transmitted light direction, be conducive to multi-faceted observation and the experiment measuring of optical phenomena, be conducive to improving experiment effect.
Description
Technical field
The utility model relates to a kind of multi-functional optical experimental device, is specially a kind of reading microscope for Newton's rings experiment.
Background technology
Newton ring is typical College Physics Experiments of Optics, will use reading microscope in this experiment, so that the equal thick interference fringe produced by Newton ring instrument carries out observing and measuring after amplifying.Sodium lamp is commonly used as light source in laboratory, vertical irradiation Newton ring instrument after being located at the half-reflecting mirror reflection below micro objective, and observes Newton ring from reflected light direction.In experiment, the position of light source, highly, all directly have influence on the image quality of interference fringe.Owing to usually needing many people to use same sodium lamp as light source in experiment, therefore light source is difficult to be applicable to multiple stage instrument simultaneously.In addition, Newton ring center should be positioned at immediately below micro objective, if be slightly offset, is then difficult to observe complete interference fringe from microscope.Experimenter is normal while, with the direct mobile Newton ring instrument of hand, observe from microscope, but Newton ring instrument is slightly done movement and is just easy to interference fringe to shift out microscopic fields of view.The problems referred to above bring inconvenience to the measurement of the observation of interference and interference fringe.
Summary of the invention
The purpose of this utility model is to do corresponding improvement for the problem in experiment to reading microscope, invents a kind of reading microscope for Newton's rings experiment.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: comprise base, vertical with base connect vertical rod, the microscope be movably fixed in vertical rod, also comprise article carrying platform, light source, illumination ring, the upper surface of base is located in described article carrying platform activity, can move forward and backward along base upper surface, article carrying platform surface is transparent glass; Described light source is located at chassis interior; Described illumination ring set is located on micro objective for irradiating article carrying platform.
Described susceptor surface is provided with the fan for chassis interior ventilation and heat.
Described light source is sodium lamp.
Owing to adopting above-mentioned design, the utility model can produce following beneficial effect: be placed on article carrying platform, immediately below micro objective as Newton ring instrument by observation thing, open light source, thing is observed in bottom-up irradiation, can observe from transmitted light direction.Open illumination ring, from up to down irradiate and observe thing, can observe from reflected light direction.Because article carrying platform can move forward and backward along susceptor surface, avoid with the hand directly mobile inconvenience observed thing and bring.The utility model avoids in experiment the inconvenience regulating light source and object of observation position etc., not only can from reflected light direction, but also can to observe from transmitted light direction, be conducive to multi-faceted observation and the experiment measuring of optical phenomena, be conducive to improving experiment effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is formation schematic diagram of the present utility model.
In figure: 1. base, 2. article carrying platform, 3 vertical rods, 4. microscope, 5. light source, 6. throw light on ring, 7. Newton ring, 11. fans, 21. transparent glass, 22. platform movement knobs, 41. object lens, 51. power interfaces, 52. light-control knobs.
Embodiment
As shown in Figure 1, the utility model comprise base 1, vertical with base connect vertical rod 3, the microscope 4 be movably fixed in vertical rod 3, also comprise article carrying platform 2, light source 5, illumination ring 6.The upper surface of base 1 is located in article carrying platform 2 activity, rotates the platform movement knob 22 being located at base 1 side surface, and article carrying platform 2 can be made to move forward and backward along base 1 upper surface, and article carrying platform 2 surface is transparent glass 21.It is inner that light source 5 is located at base 1, for irradiating article carrying platform 2 on the object lens 41 that illumination ring 6 is set in microscope 4.
Base 1 surface is provided with fan 11, the power interface 51 of light source 5, the light-control knob 52 of adjustment light-source brightness for the heat radiation of base 1 inner ventilation.
Light source 5 is sodium lamp.
The utility model, except for except Newton's rings experiment, also can be used for other Experiments of Optics such as wedge fringes.
