<p>The telescope has plane reflecting mirrors (4-1 - 6-1) situated at the rear of a primary mirror (1), and a secondary mirror (2), where one of the reflecting mirrors is oriented such that rays form a beam with a propagation direction (D1) making an angle with a radial direction of the primary mirror, after reflection on the reflecting mirror. The other two reflecting mirrors are situated between a tertiary mirror (3-1) and an image detection surface (10-1), and have respective optical axes forming corresponding angles that are less than 20 degrees, with a medium plane of the primary mirror.</p> |
