<p>An apparatus (5) for measuring the dimensions of an object (1), where a measuring carriage (6) moves along the object (1) at a distance thereabove. A polygonal mirror unit (32) receives emitted laser light (16) and reflects this in a fan-shaped form towards a stationary angled mirror unit (37, 38) which directs the light towards a double curved stationary mirror unit (39) which conducts the light beam vertically down towards the object. Means (51-57) for adjusting the mirrors (40) of the polygonal mirror unit (32), means (69-71; 69, 74) for separating out stray light and means for adjusting a diode laser (76, 97) and associated lens unit (77; 98) in relation to one another are provided.</p> |
