Abstract
An identification device for identifying identifiers on and/or features of laboratory objects and/or of samples located therein in conjunction with automated laboratory systems or facilities, for example, medical, chemical, or pharmaceutical analysis devices. Barcodes on sample containers, for example, sample tubes, reagent tubs, or microplates are used, for example, as identifiers. An optical recording unit and a mirror are used, the spacing is variable for the detection of laboratory objects, each at different distances, from a recording distance by the optical recording unit is within a depth of field of the optical recording unit. The mirror is used for imaging the laboratory object to be detected on the optical axis. The identification device is substantially simplified, more reliable, and more cost-effective in comparison to known devices that use a zoom lens together with an autofocus unit.
