High resolution wide angle lens with low distortion - is for aerial camera, contains 11 lenses, 14 lens-air boundaries in groups

摘要

The wide angle lens arrangement contains (11) lenses and (14) lens-air boundaries with (6) lenses mounted before a central stop, a scattering meniscus, a scattering dual combination group, a collecting group and (5) lenses after the stop, a collecting group, a collecting dual combination group and finally a scattering meniscus. The collecting combination group consists of a highly refractive collecting lens, a scattering lens and a further collecting lens. The collecting group after the stop contains a fluorite lens and a scattering meniscus. -
