Electronic camera objective for e.g. machine-vision imaging, having greater depth of focus at f numbers exceeding specified value, combines condenser lens with correction lens |
| 摘要 |
<p>Between diaphragm (1) and image plane, two optical components are included. One is a condenser lens dominating refraction (2). The other lens (3) provides correction, reducing distortion and image field curvature. An independent claim is included for the corresponding imaging method.</p> |
