  "textContent": "The invention relates to a device for vertically aligning a geodetic instrument above a ground point, comprising an optical observation device (10) for visually aiming at the ground point with an aiming beam (B), a laser device (11) for generating a laser beam (L), and an optical coupling element (12) by means of which the laser beam (L) and the aiming beam (B) can be coupled into a target axis (Z) that strikes the target point perpendicularly. This makes it possible to achieve precise alignment of the geodetic instrument under all lighting conditions. The geodetic instrument remains compact in its dimensions. In addition, a laser of a low hazard class can be used.",
