Abstract: A spectrometer is described, especially for an optical coherence tomograph (1) for detecting parameters of the human eye, with said spectrometer having an input for measurement radiation to be analyzed, fanning the measurement radiation spectrally out along a direction in a fan and guiding it onto a detector that extends along the direction and comprises a plurality of detector pixels that are sensitive to the measurement radiation, with the spectrometer (2) having an adjusting element (5) which can be adjusted in a controlled manner to adjust the relative position of the fan and the detector (8), thereby optimizing the incidence position (F) of the fan on the detector (8), in which it is provided that the detector (8) has at least two superimposed, adjacent pixel lines, and a control device (9) is provided which reads out the superimposed pixels of a plurality of pixel lines in a combined manner for a spectral analysis of the measurement radiation in a pixel binning and evaluates signal differences between s

Abstract: Method and device for changing the illumination light and/or specimen light with respect to its spectral composition and/or intensity in an adjustable manner, wherein a spatial separation into the radiation components of different polarization is carried out with the first polarization means (Pol 1), a spectral spatial splitting of at least one radiation component is carried out with the first dispersion means (Disp1), and the polarization state of at least one part of the spectrally spatially split radiation component is changed, wherein a reflection of the illumination light and/or the detection light is carried out.

Abstract: The invention is directed to an arrangement and a method for measuring the anterior segment of the eye using interferometric means. The eye is illuminated by a convergent beam bundle and aligned with the optical axis of the measuring device by generating directional stimuli and accommodation stimuli by means of a display which is mirrored into the beam path.
