Video microscopy arrangement for e.g. animal or human organ, has imaging lens system and lens systems to form telecentric imaging system, where lens system adjusts distance of position-changed objects by maintaining constant ratio

摘要

The arrangement (10) has an imaging lens system (2) for imaging objects (G) e.g. animal or human organ (1). A lens system (3) produces an image (B) of the objects on a recording surface (5) of a detector (6) e.g. video charge coupled device camera. The lens system is arranged in a rear focal point (F1') of the imaging system. The systems form a focusable telecentric imaging system (7). Positions (P1, P2) of the objects are changeable. The lens system adjusts distance (D) of each position-changed object by maintaining constant imaging ratio with variable focal length.
