摘要： The disclosure relates to an optical system for inspecting an eye, having an OCT system which is configured to generate a measurement beam, which is incident on an object region in a converging manner to form a measurement focus. The OCT system has a beam expander which is disposed along the measurement beam between the scanning system and the objective lens and generates an intermediate focus between the scanning system and the objective lens. The OCT system is configured to generate different values of a beam waist diameter of the beam waist by means of controlling the controllable beam expansion of the beam expander. At the different values of the beam waist diameter, an axial beam waist position of the beam waist is substantially identical.

摘要： The invention relates to a short-coherence interferometer arrangement for measuring a plurality of regions (T1, T2) of a sample (P) located at an axial distance from one another, particularly the eye (A), said interferometer comprising at least one measurement beam path through which a plurality of individual measurement beams strike the sample (P), and a reference beam path (R) through which a reference beam runs, with which the individual measurement beams (M1, M2) are overlapped and brought into interference, wherein the individual measurement beams (M1, M2), upon striking the sample (P), are axially displaced relative to one another by a quantity adapted to the axial distance (d), and the interferometer arrangement (I) overlaps each individual measurement beam (M1, M2) with the reference beam in an interfering fashion and guides said beams to the detector (D1, D2,.., DN) associated with the respective measurement beam, wherein the individual measurement beams (M1, M2,.., MN) are combined into a mixture in overlapping with the reference beam in which said measurement beams have different phase positions.
