Tube for an observation device

Abstract

A tube (10) for an optical observation device, in particular for a microscope, is described, with a viewing level that is linearly variable in length and/or height, wherein the tube (10) has an optical light path, in which at least two optical elements (23, 34) are disposed, for example, deflecting elements. The tube can be designed, for example, as a swing-in tube, with a base part (20), wherein a deflecting element (23) is disposed in base part (20) so that it can rotate around an axis of rotation (22), and with an eyepiece support (30) that can swing in relative to base part (20), wherein a deflecting element (34) is disposed in eyepiece support (30) so that it can rotate around an axis of rotation (33). In order to make possible a large swinging range, for which different viewing positions or structural lengths and structural heights of the swing-in tube (10) can be realized simultaneously for any viewing angle, it is proposed according to the invention that the optical elements (23, 34) are disposed so that they can move independently of one another in the optical light path. For example, deflecting elements (23, 34) can be disposed in a swing-in tube, so that they can rotate and/or be displaced independently of one another.
