Description
(54) ПРОЕКЦИОННЫЙ ОБЪЕКТИВ(54) PROJECTION LENS
ный из положительной 8. и отрицательной 9 линз, выполненных из баритового флинта и т желого флинта, разность покаэатблей преломлени которых составл ет 0,0856 дл Дг436 нм, а разность дисперсий - 19.from the positive 8. and negative 9 lenses made from barite flint and heavy flint, the diffraction diffraction difference of which is 0.0856 for Arg.46 nm, and the difference of dispersions is 19.
Компонент 7 - отрицательный мениск, обращенный вьтуклостью к диафрагме, выполненный из т желого флинта с соотношением радиусов 1:1,45.Component 7 is a negative meniscus facing a diaphragm, made of heavy flint with a radius ratio of 1: 1.45.
Объектив имеет преимущества перед известными: получен телецентрическнй ход лучей, увеличено поле зрени сократилось рассто ние между предметом и изображением.The lens has advantages over the known ones: a telecentric beam path was obtained, the field of view was increased, the distance between the subject and the image was reduced.
Внедрение объектива позволит повысить производительность установок, в которых ои примен етс , так как увеличилось поле зрени и вследствие телецентрического хор,а лучей в пространстве предметов отпадает необходимость в выставлении масштаба при смене фотошаблонов , отличающихс по толщине.The introduction of the lens will improve the performance of installations in which it is used, since the field of vision has increased and due to the telecentric chorus, and the rays in the space of objects eliminated the need for scaling when changing photomasks of different thickness.
