The invention refers to a method for locating an optical identification (54, 56) on a cylindrical laboratory analysis cuvette (12) containing a reagent (34), said cuvette being placed in a vertical cuvette chamber of a laboratory analyzer having a cuvette rotating device, wherein a digital camera with an axial resolution of more than 10 lines is associated with the cuvette chamber, and wherein, in fixed geometric relationship with the identification (54, 56), the cuvette (12) comprises an axial locating bar (50) with a fixed bar width. The method comprises the following steps: reading in at least four respectively non-adjacent lines of the digital camera, searching for the identification: if at least three mutually successive read-in lines comprise approximately axially in-line reflection signals with the bar width (B), reflected by the locating bar (50): rotating the cuvette (12) by an angle .alpha., .beta. corresponding to the geometric relationship, such that the identification (54, 56) is aligned with the digital camera, and reading in the identification (54, 56) by reading out a plurality of adjacent lines of the line scan camera. |
