ABSTRACT:
A guide device for the backlash-free alignment of mutually relatively displaceable parts of an optical instrument, preferably of a rack-and-pinion housing of a microscope on a profile column. The rack-and-pinion housing is constructed with a gearing such that it can be moved along the profile column. Arranged between the rack-and-pinion housing and the profile column are a plurality of sliding elements (8), which are firstly constructed resiliently and form a force-closed connection between the rack-and-pinion housing and the profile column. For the purpose of fixing in the rack-and-pinion housing, the sliding elements (8) have a receptacle (11) for inserting an adhesive. After curing the adhesive, the sliding elements (8) lose their spring action.
