Abstract
The utility model discloses a kind of reading microscope facilitating interference to observe, comprise base, vertical rod, microscope, and reflective luminescent composition plate, reflective luminescent composition plate is rectangle, its one side is plane mirror, another side is luminous plaque, and reflective luminescent composition plate is located in the face of the light inlet activity set by base side wall also can 360 degree of rotations in base.The utility model not only can utilize external light source, but also automatic light source can have been utilized to test, and can carry out Germicidal efficacy from transmitted light direction easily, checking interference law, improves 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 facilitating interference to observe.
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.Laboratory is commonly used sodium lamp and is located at microscope front as light source, and the light that light source sends is vertical irradiation Newton ring instrument after the half-reflecting mirror reflection below micro objective, observes from reflected light direction.In experiment, the position of light source, highly, all directly have influence on the image quality of interference fringe.In addition, according to the principle of interference of light, if observe Newton ring from transmitted light direction, due to optical path difference and reflected light phase difference half wavelength, interference fringe light and shade is just in time contrary with the Newton ring of reflected light.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, observes the while of inconvenient in experiment from reflected light and transmitted light both direction.The problems referred to above bring inconvenience to the measurement of the checking of the observation of interference, interference law 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 facilitating interference to observe.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: comprise base, the vertical rod that connect vertical with base, is movably fixed to the microscope in vertical rod, also comprises reflective luminescent composition plate, and described reflective luminescent composition plate is rectangle; The one side of reflective luminescent composition plate is plane mirror, for reflecting the extraneous light entering light inlet; The another side of reflective luminescent composition plate is luminous plaque, as microscopical automatic light source; Base side wall is provided with light inlet, and faced by reflective luminescent composition plate, chassis interior is located in light inlet activity, can around its horizontal symmetry axis 360 degree rotation.
The light that described luminous plaque sends is monochromatic light.
Owing to adopting above-mentioned design, the utility model can produce following beneficial effect: the plane mirror utilizing reflective luminescent composition plate, and the rear object of observation of irradiating of the light reflection injecting light inlet that external light source can be sent is observed; When lacking suitable external light source, the luminous plaque of reflective luminescent composition plate another side can be utilized to irradiate the object of observation and to observe.The utility model not only can utilize external light source, but also automatic light source can have been utilized to carry out Germicidal efficacy, when using automatic light source, the inconvenience regulating light source position, height etc. in testing can be avoided, Germicidal efficacy can be carried out from transmitted light direction easily, checking interference law, improves experiment effect.
