Description
Technical Field
The utility model relates to an even light generator technical field especially relates to an even light generator of hemisphere jar.
Background
Uniform light sources are generally desirable and it is necessary to design and manufacture specific structures to provide uniform illumination sources. The inner surface of the even light generator with the hemispherical tank structure is coated with a uniform diffuse reflection material of a high reflection material, and the proper inner coating is selected to ensure the accuracy of the result, so that the even light generator has higher reflectivity and generates multiple diffuse reflections. When incident light is incident on the inner surface of the hemisphere, multiple diffuse reflections are generated, and the incident light is converted into a uniform light beam to obtain a uniform light source through the light outlet so as to be used. The uniform light source generating structure device has no relation to the incident angle, the spatial distribution and the polarization form of incident light, and the factors can not influence the uniformity and the intensity of output light. The uniform light generator is an instrument which is widely used for measuring the light flux and the light chromaticity and is widely applied to the aspects of biomedical optics, biological tissue optics, electromagnetic wave characteristics, spectral power, scattering and the like.
It is mainly the integrating sphere to relate to more even light constructional device, all contained the hollow whole spheroid of high reflectivity coating face, inhomogeneous light source, the baffle, the receiving face, detecting instrument etc, the baffle is designed for circular or square and unsettled placing in spheroid certain position usually, prevent that the light source from directly connecing to shine on the detection face, though also can realize even light effect, nevertheless because the baffle is arranged in spheroid inside and unsettled, it is comparatively difficult to make it fixed to become, also can bring the trouble in manufacturing, it is also not very convenient in actual operation, also do not contribute to the using widely and the imaging principle of full play optics of even light source.
The utility model has the following contents:
the to-be-solved technical problem of the utility model is: the utility model provides a even light generator of hemisphere jar, place in spheroid certain position for circular or square and unsettled by the design for solving the even light constructional device baffle of prior art usually, prevent that the light source from directly connecing to shine on the detection face, even can realize even light effect, nevertheless because the baffle is arranged in spheroid inside and unsettled, it is comparatively difficult to make it fixed, also can bring the trouble in the manufacturing, it is also not very convenient in actual operation, also do not contribute to the technical problem such as use widely of even light source and the imaging principle of full play optics.
The utility model adopts the technical scheme that:
A hemispherical can homogenizing light generator comprising: the semi-spherical tank is arranged at the bottom of the semi-spherical tank; the center of the bottom of the hemispherical tank is provided with a uniform light source light outlet; the non-uniform light source is fixed around the light outlet of the uniform light source.
The non-uniform light source is fixed on the mounting base; the mounting base is fixed on the bottom of the hemispherical tank; the non-uniform light sources are uniformly arranged around the light outlet of the uniform light source.
The inner wall of the hemispherical tank is coated with a reflective material, and the reflective material is uniformly sprayed on the inner wall of the hemispherical tank; the reflecting material is magnesium oxide or barium sulfate.
The upper surface of the bottom of the hemispherical tank adopts a mirror surface as a baffle or adopts a Lambertian surface formed by a diffuse reflection material as the baffle.
The radius of the light outlet of the uniform light source is 20-25% of the radius of the hemispherical tank.
The non-uniform light source is a light emitting diode or a laser light source.
The utility model has the advantages that:
The utility model discloses an even light generator places in hemisphere tank bottoms portion through with built-in inhomogeneous light source, owing to have a plurality of built-in light source installation bodies, can use the light source of different grade type to mix, forms even mixed light through diffuse reflection many times, also can use single light source, can select according to actual need. The non-uniform light source of the uniform light generator selects the light emitting diode, and the light color of the light emitting diode is pure, so that the light color is more favorable for generating a uniform light source.
The utility model discloses a hemisphere jar is that the inner wall has the hollow sphere of high reflecting material, and even light source export should not be too big or too little, and too big can make the light source of formation not even enough, exports too little also can influence the anticipated effect of the light source of formation.
the utility model discloses a fix inhomogeneous light source installation spheroid in hemisphere tank bottoms portion, and the position of placing be hemisphere bottom surface on the border ring. The light emitted from the bottom light outlet is just a required uniform light beam; the inner wall of the hemispherical tank is sprayed with a high-reflection material, the reflection material has a good reflection effect, the sprayed reflection material is uniform and has moderate and consistent thickness, and the radius of the integral hemispherical tank is equal everywhere; light rays of the non-uniform light source arranged at the bottom of the hemispherical tank irradiate the inner wall of the integrating sphere through the non-uniform light source light outlet of the non-uniform light source installation sphere, and then are subjected to diffuse reflection on the inner wall of the integrating sphere for a plurality of times to the uniform light beam outlet at the bottom of the hemispherical tank to form uniform light beams. The light uniformizing device of the utility model is simple relative to the integrating sphere, and the size is reduced by half relatively; the manufacturing process is simple, so the cost is reduced on the whole, the problem that the production and manufacturing cost of the current uniform light source generator is higher is solved, and the principle that laboratory optical imaging cannot be fully utilized is improved; the use and development of uniform light sources are promoted; the even light constructional device baffle of prior art is designed for circular or square and unsettled placing in spheroid certain position usually, prevents that the light source from directly connecing to shine on the detection face, though can also realize even light effect, nevertheless because the baffle is arranged in spheroid inside and unsettled, it becomes comparatively difficult to make it fixed, also can bring the trouble on manufacturing, also can be not very convenient in actual operation, also does not benefit to technical problems such as the use widely of even light source and the formation of image principle of full play optics.
