KORSCH-TYPE COMPACT THREE-MIRROR ANASTIGMAT TELESCOPE |
| 摘要 |
A three-mirror anastigmat telescope comprises at least a concave first mirror, a convex second mirror and a concave third mirror, the three mirrors arranged so that the first mirror and the second mirror form, from an object at infinity, an intermediate image situated between the second mirror and the third mirror, the third mirror forming, from this intermediate image, a final image in the focal plane of the telescope. In the architecture of the telescope, at least the surface of the concave third mirror is a φ-polynomial surface. |
