PROBLEM TO BE SOLVED: To provide and develop a tube of such a kind that the interval from the operator of a microscope to the microscope can be changed in a specified direction while an observing angle is maintained. SOLUTION: The tube to be adapted to the microscope has a tube housing (3), an adaptable interface (4), a beam diffracting unit (5), a further beam guiding means (7) and an operator interface (8). A light beam coming from the interface (4) is refracted by the unit (5) so that its optical axis (6) is at least locally extended on a specified surface substantially, and guided to the interface (8) by the guiding means (7). The housing (3) is constituted to move relatively in a direction parallel with a specified surface with respect to the microscope (2) together with the guiding means (7) and the interface (8) in order to maintain the observing angle, while the interval from the interface (8) to the microscope is changed in the specified direction.
