Abstract
Described is a tube (20) for a viewing device (10), particularly for a microscope, the tube (20) having at least one viewing beam path--for example, two viewing beam paths (21, 22). Provided in the at least one viewing beam path is at least one optical tube element. In order to reduce the structural length of the viewing device (10), it is provided for in accordance with the invention that a magnification system (23) for changing the focal depth--for example, a zoom system--is further arranged in the viewing beam path of the tube (20) itself. In the case of several viewing beam paths, a magnification subsystem (24, 25) for changing the focal depth can be arranged, for example, in each of the viewing beam paths (21, 22) of the tube. Further described is a corresponding viewing device (10).
