Abstract
An identification device, especially one for detecting unidimensional and/or two-dimensional codes, which has a position-resolving photoreceiver arranged in a housing and a reception optics coordinated with it and also installed in the housing. The entire reception optics and the position-resolving photoreceiver are immovably mounted in a housing of the identification device. For focusing at different object distances, an effective optical back focal distance is changed with only an adjustable deflection mirror that is positioned between the photoreceiver and the reception optics.
