Abstract:
1. A spectrometer for detecting parameters of the human eye, comprising: a detector extending along a detection direction, the detector including a plurality of detector pixels that are sensitive to a measurement radiation, the detector also including at least two adjacent pixel lines that are stacked on top of each other; an input port for receiving the measurement radiation to be analyzed, the input port configured to fan the measurement radiation spectrally out along a first direction and guide the fanned measurement radiation onto the detector; an adjusting element configured to controllably adjust the relative position of the fanned measurement radiation and the detector; a control device which evaluates signal differences between two or more pixels in the stacked pixel lines, controls the adjusting element, and centers the incidence position of the fanned measurement radiation perpendicular to the detection direction of the at least two adjacent pixel lines.
