Изобретение огносигс к технические физике в части измерени световых потоков , в частности, дл измерени квантового выхода полупроводников.The invention of fire ogneigs to technical physics in terms of measuring light fluxes, in particular, for measuring the quantum yield of semiconductors.
Известны фотометры, . предназначенные дл измерени р да параметров световых пот(Ж(№ с помощью электрических детектсрсю излучени , содержащие юстирсдаочную юптику и электрический преобразователь Ц.Known photometers,. designed to measure a series of parameters of light sweats (F (No. using electrical radiation detectors, containing an adjustment gearbox and an electrical transducer Z.
Недостатком известных устройств в ,л етс низка точность измерени , обусл жленна потерей информации из-за ог раничш1ных возможностей линейной оптики .A disadvantage of the known devices is that the measurement accuracy is low, due to the loss of information due to the limited possibilities of linear optics.
Наиболее близким к изобретению авл етс фотометр, содержащий интегр1фующую сферу, на внутренней поверхности котор расположена приемна поверхность фотоп{жемвика. Устройство позвол ет с аостаточной точностью измер ть такой параметр световых потоков, как мощность излучени 12.The closest to the invention is a photometer containing an integral sphere, on the inner surface of which is the receiving surface of the fotop {gemstone. The device makes it possible to measure such a parameter of light fluxes as radiation power 12 with adequate accuracy.
Однако известное ус1ройство не позвол ет непосредственно измер ть кванты света, так как дл этого предварительно необходимо измерить специальное расЕфеделенне исследуемого излучени . При этом неизбежны дополнительные пс решности, котсрые снижают тотаость измерени квантов света.However, the known device does not allow to directly measure the quanta of light, since for this purpose it is first necessary to measure the special separation of the investigated radiation. In this case, additional resoluteness ps are inevitable, which reduce the measurement of light quanta.
Известные фотометры не имеют плав .коА регулир №ки спектральной чувствительности . Она осуществл етс дискретно путем смены светофильтров.Famous photometers do not have a float. BoA regulator No. spectral sensitivity. It is carried out discretely by changing the filters.
Цель изобретени - непосредственное измерение квантов света и повышение точности измерени . The purpose of the invention is the direct measurement of light quanta and improvement of measurement accuracy.
Поставленна цель достигаетс тем, что в фотометре, содержащем интегрирующую сферу, на внутренней поверхности которой расположена приемна поверхность фотоориемника, : и регул тор спектральной чувствительности фотоприемника, последний установлен внутри сThe goal is achieved by the fact that in a photometer containing an integrating sphere, on the inner surface of which the receiving surface of the photo-receiver is located,: and a regulator of the spectral sensitivity of the photodetector, the latter is installed inside with
