Description
(54) СПЕКТРОФОТОМЕТР(54) SPECTROPHOTOMETER
1one
Изобретение относитс к технике оптических измерений и может быть использовано при колориметрических измерени х и контроле цветовых характеристик объектов/ например текстильных материалов.The invention relates to optical measurement techniques and can be used in colorimetric measurements and control of color characteristics of objects / for example, textile materials.
Известны спектрофотометры дл контрол колориметрических характеристик объектов, содержащие монохроматор и фотоэлектрический измерительный тракт 1 .Spectrophotometers are known for monitoring the colorimetric characteristics of objects containing a monochromator and a photoelectric measuring path 1.
Недостатком указанного спектрофотометра вл етс низка производительность , поскольку дл получени спектральной зависимости коэффициента отражени объекта необходимо последовательно измерить оптические характеристики объекта в каждом спектральном интервале в пределах выбранного диапазона.The disadvantage of this spectrophotometer is low productivity, because in order to obtain the spectral dependence of the reflection coefficient of an object, it is necessary to measure the optical characteristics of the object in each spectral range within the selected range.
Наиболее близким к предлагаемому вл етс спектрофотометр, содержащий источник пучков света различного спектрального состава, модулированных по амплитуде с разными частотами , оптическую схему измерени характеристик образца и фотометрический Тракт, причем источник пучков света через оптическую схему св зан с фотопреобразователем фотометрического тракта, который через последовательно соединенные усилите.чг,- и схв му частотного разделени каналов, подключен к регистратору 2.The closest to the present invention is a spectrophotometer containing a source of light beams of different spectral composition modulated in amplitude with different frequencies, an optical circuit for measuring the characteristics of the sample and a photometric path, the source of light beams connected through an optical circuit to a photometric transducer of the photometric path through which Amp., and the frequency division link, connected to recorder 2.
Это устройство позвол ет производить измерени оптических хара.ктеристик объекта одновременно в нескольких спектральных интервалах.This device allows measurements of the optical characteristics of an object at the same time in several spectral intervals.
Недостатком известного спектро10 фотометра вл етс низка точность измерений, обусловленна временной нестабильностью интеноивности источника света и коэффициента усилени фотометрического тракта.A disadvantage of the known spectrometer of a photometer is the low measurement accuracy due to the temporary instability of the intensity of the light source and the gain of the photometric path.
