Abstract
The utility model relates to a technical filed of optical equipment, in particular to a quick color measuring device, which comprises an optical path system and a control circuit. The optical path system comprises a plurality of lighting sources, a first optical grating, a tunable optical filter, a second optical grating and an integrating sphere which are arranged in sequence. The control circuit is connected between the integrating sphere and the tunable optical filter, and polarizing sheets are respectively arranged at two ends of the tunable optical filter. The lighting sources are focus lamps, thereby reducing the volume of the quick color measuring device, lowering energy consumption, reducing temperature rise and accordingly ensuring accuracy of the quick color measuring device. In addition, the quick color measuring device adopts the acousto-optic tunable optical filter as an optical splitter in the optical path system to perform spectral scan, thereby maintaining color measuring accuracy of an original spectrophotometer and improving color measuring speed.
Description
Technical field:
The utility model relates to the optical devices technologies field, refers in particular to quick detector of colour.
Background technology:
Existing measurement is the optical instrument of look quite, generally is divided into two big types.One type is the photoelectric integration color measurement instrument, and it is to utilize the photoelectric integration device with special spectrum sensitivity, direct measurement light source look or object values or chromaticity coordinate, its side look speed is fast but precision is low.Another kind of for the colour examining spectrophotometer, it is through light-splitting device object to be carried out spectral luminosity to measure, and records the spectral reflectance factor or the spectral-transmission favtor of object, through data processing, computing and then draw values and the chromaticity coordinate of object color.But its shortcoming is that colour examining speed is slow, and generally doing a colour measurement needs second-time even above time of branch, is difficult to carry out survey dish in real time with it, and its application is restricted.
The utility model content:
The purpose of the utility model is exactly to the deficiency of prior art existence the quick detector of colour that a kind of colour examining speed is fast, the colour examining precision is high, volume is little to be provided.
To achieve these goals; The technical scheme that the utility model adopts is: quick detector of colour, include light path system and control circuit, and light path system includes lighting source, first grating, tunable filter, second grating, the integrating sphere that sets gradually; Control circuit is connected between integrating sphere and the tunable filter; The two ends of tunable filter are respectively equipped with polaroid, and lighting source is a plurality of, and lighting source is a spotlight.
A plurality of lighting sources are positioned on the same plane parallel with first grating, and a plurality of lighting sources along the circumferential direction evenly distribute.
The said second grating slope setting, angle of inclination are 60 degree.
The utility model beneficial effect is: the quick detector of colour that the utility model provides, include light path system and control circuit, and light path system includes lighting source, first grating, tunable filter, second grating, the integrating sphere that sets gradually; Control circuit is connected between integrating sphere and the tunable filter; The two ends of tunable filter are respectively equipped with polaroid, and lighting source is a plurality of, because lighting source is a spotlight; Can reduce the volume of the utility model; Reduce energy consumption, reduce temperature rise, corresponding assurance the utility model precision; And the utility model adopts acousto-optic tunable filter to carry out spectral scan as the light-splitting device in the light path system, makes the colour examining precision that had both kept original spectrophotometer in the utility model, has improved colour examining speed again.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, sees shown in Figure 1ly, the utility model includes light path system and control circuit 1; Light path system includes the lighting source that sets gradually 2, first grating 3, tunable filter 4, second grating 5, integrating sphere 6, and control circuit 1 is connected between integrating sphere 6 and the tunable filter 4, and the two ends of tunable filter 4 are respectively equipped with polaroid 7; Lighting source 2 is a plurality of, and lighting source 2 is a spotlight, owing to used spotlight; Can reduce the volume of the utility model; Reduce energy consumption, reduce temperature rise, corresponding assurance the utility model precision.
A plurality of lighting sources 2 are positioned on the same plane parallel with first grating 3, and a plurality of lighting sources 2 along the circumferential direction evenly distribute, and improve the uniformity of light that a plurality of lighting sources 2 send.Second grating 5 is obliquely installed, and the angle of inclination is 60 degree.
The utility model adopts acousto-optic tunable filter 4 to carry out spectral scan as the light-splitting device in the light path system, makes the colour examining precision that had both kept original spectrophotometer in the utility model, has improved colour examining speed again.
Certainly, the above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
