Изобретение относится к приборостроению и может быть использовано при контроле диаметров входных зрачков фотообъективов. Задачей изобретения является создание устройства оперативного контроля диаметров входного зрачка фотообъектива. Для решения поставленной задачи в устройство оперативного контроля соответствия диаметров входных зрачков фотообъектива интервалам допустимых значений, содержащее последовательно расположенные и оптически связанные источник света, коллиматор, калибровочную диафрагму, контролируемый объектив, расположенный в фокальной плоскости контролируемого объектива фотоприемник и измерительный прибор, введены регулируемый блок питания, соединенный с источником света, и фильтр, вход которого соединен с выходом фотоприемника, а выход - с измерительным прибором.The invention relates to instrument making and can be used to control the diameters of the entrance pupils of photographic lenses. The objective of the invention is to create a device for operative control of the diameters of the entrance pupil of a photo lens. To solve the task, a device for operative control of the correspondence of the diameters of the entrance pupils of the photo lens to the intervals of acceptable values, containing successively located and optically coupled light source, collimator, calibration aperture, controlled lens, photodetector and measuring device in the focal plane of the controlled lens connected to the light source, and the filter, the input of which is connected to the output of the photodetector, and the output - to measure telny device.
