Afocal four-mirror system for optical telecommunication |
| 摘要 |
<p>The multiple-mirror system has aspherical mirrors (3-9) with which high magnification is achieved, whereby central shadowing is prevented with at least two mirrors tilted with respect to the optical axis. At least three of the mirrors of a four-mirror system or the fourth mirror are spherical.</p> |
