Description
составл ют в этом примере приблизительно 54° и 88°. У склеенных линз разпость показателей преломлени больше 0,05 и разность коэффициентов дисперсий больше 20,0.in this example, approximately 54 ° and 88 °. In glued lenses, the refractive index difference is greater than 0.05 and the difference in the dispersion coefficients is greater than 20.0.
Предмет изобретени Subject invention
Объектив, содержащий систему кругового обзора из выпуклого и вогнутого соосных копусов и два линзовых компонента, отличающийс тем, что, с целью улучшени коррекции аберраций по всему полю зрени , первый линзовый компонент выполнен однолинзовым, жестко соединен с выпуклым конусом, а разность показателей преломлени и коэффициентов дисперсий линз склеенного компонента превышает 0,05 и 20,00 соответственно.A lens containing a circular viewing system of convex and concave coaxial copuses and two lens components, characterized in that, in order to improve the correction of aberrations across the entire field of view, the first lens component is single-lens, rigidly connected to a convex cone, and the difference between the refractive indices and coefficients dispersions of the lenses of the glued component exceeds 0.05 and 20.00, respectively.
