Description
В фотографии, дл получени отпечатков различной контрастности, что особенно , важно при печатании кинолент, при процессе печатани приходитс поль зоватьс набором цветных стекол. В предлагаемом приборе дл копировани роль цветйых стекол выполн ет пучок света, разложенного на. спектральные цвета.In photography, to obtain prints of different contrast, which is especially important when printing films, during the printing process one has to use a set of colored glasses. In the proposed copying device, the role of the colored glass is performed by the beam of light disintegrated on. spectral colors.
Изображенный на схематическом чертеже прибор дл копировани состоит из поворотно установленной около оси 4 призмы 3, отделенной перегородками 5 от помещени с рефлектором 1 и отражающей плоскостью 2. В Окне 6 продвигают Позитивную и негативную пленки. В центре рефлектора 1 помещают источник белого света. Отраженные лучи параллельным пучком падают на расположенную под некоторым углом плоскость 2. Отразившись от этой плоскости, луч попадает на грань пр зт ы 3. При копировании призму 3 устанавливают так, чтобы на окно 6 падал пучок разложенного .вета.The copying device shown in the schematic drawing consists of a prism 3 pivotally mounted about axis 4, separated by partitions 5 from a room with a reflector 1 and a reflecting plane 2. In Window 6, Positive and Negative films are advanced. In the center of the reflector 1 place a source of white light. Reflected rays of a parallel beam fall on a plane 2 located at a certain angle. Reflecting from this plane, the beam hits the face of prt s 3. When copying, prism 3 is set so that a window of decomposed light falls on window 6.
окрашенный в избранный цвет, чем достигают изменени контрастности копируемых снимков. Перегородки 5, вращающиес вместе с призмой 3, преп тствуют проникновению белйх лучей света к окну 6 во врем поворота призмы 3.colored in the selected color, thus achieving changes in the contrast of the copied images. The partitions 5 rotating with the prism 3 prevent the white light from entering the window 6 during the turn of the prism 3.
