Optical system with astigmatism compensation. |
| 摘要 |
<p>The present invention is directed to compensation plates (2) for eliminating astigmatism and coma optical aberration in optical systems. In particular, the present invention can be used in LCD projection systems to compensate for aberrations in different colour channels (6-1, 5-1, 4-1). This enables the production of LCD systems completely free of astigmatism and/or coma. <IMAGE></p> |
