| Zusammenfassung: | The present invention is a dark field illumination system including a light source which is focused on an annular entrance slit (64) of a condenser and an objective (12) aligned with the condenser such that the objective and the condenser are adjusted to find a focus spot on a sample (32). The present invention essentially uses structured illumination to achieve an improved illumination system. The present invention also includes a system and method wherein the objective is coupled to an iris (65) and aligned with the condenser such that when the iris is closed only dark field images are produced, and when the iris is open, direct entrance of light is allowed into the objective and bright field illumination is produced. |
