DEVICE FOR ALTERNATELY REALIZING THE MICROSCOPIC OBSERVATION IN PHASE CONTRAST OR IN RELIEF |
摘要 |
The invention contemplates a microscope construction, applicable both to reflected-light and to transmitted-light varieties, whereby an object under examination can be selectively observed for phase-contrast and for relief effect (so-called "contrast modulation"). A first diaphragm having the effective shape of a circular ring is selectively positionable concentric with the observation-ray path and at a first location conjugate to the image plane of the microscope objective; and at least two diaphragms are selectively positionable on the illumination-ray path at a second location conjugate to the image plane of the microscope objective. One of these latter two diaphragms is in the effective circular-ring shape of the observation-path diaphragm, and the other of these latter two diaphragms is a light-transmitting circular-ring segment. |
