The invention relates to an OCT system, comprising: an OCT light source for emitting OCT light into an object beam path and a reference beam path; and a detector for capturing an interference signal produced from the object beam path and the reference beam path. A wavelength-dependent beamsplitter is arranged in the OCT beam path such that a first spectral partial beam is guided along a longer path and a second spectral partial beam is guided along a shorter path. The invention further relates to a corresponding OCT method. Two measurement regions separated from each other can be sensed by means of the OCT system according to the invention.

OCT system and OCT method

The invention relates to an OCT system with an OCT light source for emitting OCT light into an object beam path and a reference beam path. The system comprises a detector for detecting an interference signal produced by the object beam path and the reference beam path. A polarization-dependent delay element is arranged in the object beam path. The invention also relates to a corresponding OCT method. The invention allows the effects of parasitic reflections to be reduced.

In a method for registering measurement points on a body, in particular on an eye, measurement points are registered along a trajectory on a surface of the body, in particular a curved surface of the body, for determining an axial length profile, by way of a measurement beam. Here, a minimum radius of curvature of the trajectory is at least 1/7, preferably at least &#x2155;, particularly preferably at least &#x2153; of a radius of a circumference of the surface.

Measuring method

An adapter () for an apparatus () for measuring a first property of an eye is attachable to the apparatus (), wherein, when the adapter () is attached to the apparatus (), a second additional property of the eye is measurable.
