Abstract

Technical field: the utility model relates to a spectrum integral formula color measurer, belonging to the color measurer field. The characteristic is that, the illumination light source is composed of a pulsed xenon arc lamp. The measure optical path and the reference optical path are both provided with a measuring photoconductive fiber bundle and a reference photoconductive fiber bundle. The photoconductive fibers bundles are respectively provided with a light inlet end and a plurality of outlet ends, each of which is provided with corresponding optical filters and receivers therebehind. The measuring bundle and the reference bundle are conducted to the corresponding optical filters and receivers through each corresponding measuring photoconductive fiber bundle and reference photoconductive fiber bundle so that the measuring bundle and the reference bundle can be transmitted into three groups of optical filters and receivers, X (Lambda),Y (Lambda),Z (Lambda)at the same time.

Description

Spectrum integral formula colour photometer

Technical field: the utility model relates to a kind of spectrum integral formula colour photometer, belongs to color measurement instrument.

Background technology: spectrum integral formula colour photometer is to utilize the photoelectric integration element with special spectrum sensitivity, direct measurement light source look or the tristimulus values of object color or the instrument of chromaticity coordinate, owing to can be designed to the portable of compact conformation and can use, become the color measurement instrument that generally uses in the commercial production so far in the production scene.The lighting source of instrument adopts light filter to proofread and correct, make it have the spectral power distribution of desired " standard illuminants ", also to use the light filter correction to the spectral response of receiver simultaneously, make it consistent with " CIE " standard colorimetric observer, make the spectrum sensitivity of instrument can meet " simulation " requirement, promptly must meet " Luther condition ".Because collecting the geometric condition of luminous energy, light illumination and detector directly influence measurement structure, be unified measurement result, CIE has stipulated four kinds of flash ranging geometric conditions: 45/0,0/45,0/d, d/0, and the angle between the normal of the beam axis of angle between illumination beam optical axis and sample surfaces normal and observed ray and sample surfaces has all been made strict regulation, therefore the color measurement instrument of spectrum integral formula generally can only be selected a kind of standard illuminants (C or D65) and selected a kind of standard colorimetric observer (1931 standard colorimetric observer's spectral tristimulus values or 1964 replenish standard colorimetric observer's spectral tristimulus value) for use, when specific design, the light filter of light source and receiver can be merged into one group designs, with X (λ), Y (λ), three light filters of Z (λ) are installed in respectively in the rotating disk, with manually or utilize electronic technology control step motor to rotate will every in the light filter insertion flash ranging light path, by comparing and measuring to " standard sample " and " sample ", obtain spectral tristimulus value, also have in flash ranging mechanism, install three in the angle of regulation and receive only the spectral radiance value that device receives " sample " simultaneously, be limited to above-mentioned reason, so do not see as yet that up to the present being a spectrum integral formula color measurement instrument can measure illuminant-C (standard illuminants sample) simultaneously, 1931 standard colorimetric observer's spectral tristimulus values and D65 light source (standard illuminants sample) 1964 replenishes the color measurement instrument of standard colorimetric observer's spectral tristimulus value, because reach this two kinds of " colour examining " functions, must there be six light filters or six assembly that signal receiver by the Luther condition calculation Design is arranged, be difficult on the structure arrange, and under the flash ranging geometric condition of regulation the every technical requirement that is difficult to accomplish the conformance with standard regulation, perhaps to repeatedly calibrate, item by item test.

Summary of the invention: the purpose of this utility model is to provide a kind of spectrum integral formula colour photometer that can obtain the multiple CIE standard colorimetric observer spectral tristimulus value under multiple standards working flare condition quickly and easily for overcoming the prior art deficiency.

The technical solution of taking for the realization the purpose of this utility model is as follows: spectrum integral formula colour photometer comprises lighting source, light filter, receiver, processing unit and shell, lighting source one tunnel irradiation sample produces measuring beam through measuring light filter, measure receiver and deliver to processing unit formation measurement light path, another road as reference beam through the reference light filter, the reference optical receiver is delivered to processing unit, form double light path photoelectricity compensation flash ranging structure, constitute lighting source by the pulsed xenon arc lamp, measure in light path and the reference light paths and be equipped with non-contact measurement of optical fiber bundle and reference fibre-optic bundle, fibre-optic bundle respectively is provided with a light inputting end and a plurality of output terminal, be provided with corresponding light filter and receiver behind each output terminal, measuring beam and reference beam conduct to corresponding light filter and receiver through each self-corresponding non-contact measurement of optical fiber bundle and reference fibre-optic bundle respectively.

Because fibre-optic bundle flexible, therefore light filter and receiver can be laid according to the actual conditions in instrument internal space, needn't be by certain geometric relationship, can make full use of the space and lay many light filters or many assembly signal receiver by the Luther condition calculation Design is arranged; In addition, fibre-optic bundle adopts a light inputting end, the structure of afterbody bifurcated, the measuring beam reference beam can be passed on X (λ), Y (λ), three groups of light filters of Z (λ) and the receiver simultaneously, processing unit is disposable to obtain correlation parameter simultaneously, thereby calculates spectral tristimulus value, has made things convenient for use, shorten Measuring Time, can also obtain various criterion colourity observer spectral tristimulus value under the multiple various criterion working flare simultaneously.

The utility model is described in further detail and provide embodiment simultaneously below in conjunction with accompanying drawing.
