Summary
Description Bouwers meniscus telescope concentric.svg |
English:
The
Albert Bouwers
concentric
meniscus telescope
patented it in February of 1941. This
catadioptric telescope
design had the spherical mirror and spherical
negative meniscus lens
with all surfaces concentric with a common radius of curvature (C). The design had an ultra wide field of view but did not correct
chromatic aberration
and was only suitable as a monochromatic astronomical camera.
Русский:
Менисковая камера Шмидта. (Менисковый Шмидт Максутова-Бауэрса). Схема состоит из главного сферического зеркала, сферического концентрического мениска и диафрагмы, расположение которой совпадает с центром сферических поверхностей зеркала и мениска. Все сферические поверхности лежат и выпуклы по одну сторону от диафрагмы. Обладает очень широким полем зрения, в ущерб недоисправленным сферической и хроматическим аберрациям. В виду отличия мениска от параметров ахроматического мениска телескопа Максутова, хроматизм не исправлен и обладает большой величиной. Может используется для фотографии в монохроматическом свете. Альбертом Бауэрсом (
Albert Bouwers
) запатентован в годы Второй мировой войны, в феврале 1941, но до её окончания не был опубликован.
