Abstract
The utility model relates to an integrating sphere. The integrating sphere mainly comprises a main body and a diffusion device; wherein, the main body is in spherical shape and is provided with hollow diffusion space; a base is arranged at the bottom of the main body; the diffusion device is arranged in the diffusion space and is equipped with a tapered cone; an incidence hole is arranged at the center of the top of the main body and is used for the incidence of incident light; and an induction probe is arranged at a position corresponding to the incidence hole on the main body for the measurement of the integrating sphere. The tapered cone of the diffusion device provides a better incidence surface for the incident light; due to the arrangement of the base, the integrating sphere can be stably arranged on the ground by the user; in addition, when the incident light source is arranged in the incidence hole, the center of gravity of the incident light source faces the direction of the spherical center in the diffusion space; and the light beams of the incident light source has no slight deviation as a result of the deflection of the center of gravity, which prevents the resulting error of measured numeric values.
Description
Technical field
The utility model is a kind of integrating sphere, refers to a kind of light source generator that produces even distribution light source especially.
Background technology
In order to reduce inequality distribute and incident light skew caused the error of optical detecting device because of incident light source, conventional art is to use optical diffusion sheet to improve the accuracy of measurement; Yet for the accuracy of its measurement can more be improved, the optical diffusion sheet that the present overwhelming majority is used to measure has been integrated ball and has replaced.
Can make measurement result more accurate, reliable by integrating sphere; Because of integrating sphere can reduce and remove the measuring error that is caused because of light shape, dispersion angle and detector position, impelling its incident light is equally distributed light source.Please refer to Fig. 4, disclose basic structure and principle of work thereof that integrating sphere 90 is arranged on it, when incident light via can be decomposed when monochromator (mono-chromator) 91 in the integrating sphere 90 is injected in hole 92 light source of each different-waveband of injecting of a side.Because its employed light source is not to be one can send the light source of even distribution directional light, therefore, light source is evenly distributed so the light that this light source produced need see through integrating sphere 90 in order to obtain to be used for measuring the light source of determinand character.At this moment, utilize light source irradiation that integrating sphere 90 internal emission come out to sensing head, to measure the luminous flux (lumen) of determinand again.
Yet traditional integrating sphere 90 need additionally be established an erecting frame to fix this integrating sphere position, to make things convenient for user's measurement.In addition, the incident light source position of this integrating sphere 90 is located on the side of integrating sphere 90, therefore wants very careful when placing incident light source.Its reason is: the stressed of this light source is directed downwards, and its joint be subjected to force direction towards integrating sphere 90 inboards, therefore when light source is installed, this light source is subjected to force direction different because of gravity own and joint, so when light source is installed on integrating sphere 90 1 sides, produce crooked easily, and make its incident light that sends produce skew, cause the error of measurement.So, the real necessity that further improvement is arranged of the structure of this integrating sphere.
Summary of the invention
Therefore, the utility model fundamental purpose is to provide a kind of integrating sphere, the set-up mode of its incident light source can avoid incident light source crooked because of what gravity produced, impels the light source that this integrating sphere produces can more even distribution, and makes its measured determinand numerical value can be more accurate.
For reaching the technological means that above-mentioned purpose takes is to make aforementioned integrating sphere comprise:
One body, be hollow form, its inside has a diffusion space spherical in shape and this body and has and a Z-axis by the diffusion space centre of sphere parallel with gravity direction, this body forms one in the top of Z-axis and injects the hole, infeed and penetrate the usefulness that light is injected, and this body forms a sensing head in the other end of Z-axis, and this body extends a pedestal downwards in outer lower end again; And
One diffusing device, be located in the diffusion space of above-mentioned body, this diffusing device has a cone-shaped cone, this cone has an awl point, this awl point points to centre of sphere direction, and this cone base extends outward a plurality of fixing rib of joining with body respectively, this cone is fixed in injects between hole and sensing head by this.
Utilize said structure, with this incident light source be located at the body top inject the hole time, because of the setting and the gravity direction of this incident light source is parallel to each other, therefore can make the centre of sphere direction of this incident light source center of gravity towards the diffusion space, and the light that this incident light source is produced can not be provided with the deviation slightly that is produced because of it, and makes this integrating sphere cause the error of measuring when the measuring light flux.In addition, the cone-shaped cone of this diffusing device can provide incident light to do better diffusing surface, and the setting of its pedestal can guarantee that then the user places integrating sphere on the ground reposefully.
