Summary

Description
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.
