Abstract
Изобретение относитс к измерительной технике и может быть использовано дл бесконтактного оптического контрол дефектов торцовых поверхностей прозрачных трубок при производстве газоразр дных ламп. Цель изобретени - расширение области применени за счет обеспечени возможности контрол дефектов торцовых поверхностей прозрачных трубок. В устройстве фотоприемник выполнен в виде тела вращени второго пор дка с четырьм плоскими щелеобразными фотоэлементами дл приема отраженного излучени . Благодар этому по вл етс возможность проследить всю торцовую поверхность контролируемой трубки.2 ил.The invention relates to a measuring technique and can be used for non-contact optical inspection of defects on the end surfaces of transparent tubes in the manufacture of gas discharge lamps. The purpose of the invention is to expand the scope of application by allowing the inspection of defects on the end surfaces of transparent tubes. In the device, the photodetector is made in the form of a second-order rotation body with four flat slit-like photocells for receiving the reflected radiation. Due to this, it is possible to trace the entire end surface of the test tube. 2 Il.
